Description

BACKGROUND

Technical Field

The disclosure relates to a pixel array substrate.

Description of Related Art

With the development of display technology, people's requirements for display devices are no longer satisfied with optical characteristics such as high resolution, high contrast, and wide viewing angle. People also expect display devices to have an elegant appearance. For example, people expect a display device to have a narrow bezel or even no bezel.

Generally speaking, the display device includes multiple pixel structures disposed in a display region, a data driving circuit disposed below the display region, and a gate driving circuit disposed on the left, right, or left and right sides of the display region. In order to reduce the width of the left and right sides of the bezel of the display device, the gate driving circuit and the data driving circuit may be both disposed on the lower side of the display region. When the gate driving circuit is disposed on the lower side of the display region, gate lines arranged in the perpendicular direction need to be electrically connected to the gate driving circuit through transfer lines arranged in the parallel direction. However, the gate-on pulse signal of the transfer line affects the potential of other pixel structures that are still charging, thereby causing a display abnormality (for example, diagonal bright lines). Therefore, how to improve the display abnormality is one of the challenges faced by current ultra-narrow bezel display devices. In addition, how to improve the aperture ratio of the display device and enable the display device to be less prone to the appearance of bubbles are other challenges.

Please refer to FIG. 1 and FIG. 2. The (x−n)-th scan line HGx−n to the (x+n)-th scan line HGx+n respectively have a gate pulse signal S_HGx−n to a gate pulse signal S_HGx+n.

A time length of the time delay is t (shown in FIG. 2), and a pulse time length of each of the gate pulse signal S_HGx−n to the gate pulse signal S_HGx+n is Tp (shown in FIG. 2), where n=Tp/t. A start time tonx of the gate pulse signal S_HGx of the x-th scan line HGx and an end time toffx−n of the gate pulse signal S_HGx−n of the (x−n)-th scan line HGx−n overlap in time sequence. In other words, a time period when the gate pulse signal S_HGx of the x-th scan line HGx rises from a low potential Vgl to a high potential Vgh and a time period when the gate pulse signal S_HGx−n of the (x−n)-th scan line HGx−n drops from the high potential Vgh to the low potential Vgl at least partially overlap in time sequence. An end time toffx of the gate pulse signal S_HGx of the x-th scan line HGx and a start time tonx+n of the gate pulse signal S_HGx+n of the (x+n)-th scan line HGx+n overlap in time sequence. In other words, a time period when the gate pulse signal S_HGx of the x-th scan line HGx drops from the high potential Vgh to the low potential Vgl and a time period when the gate pulse signal S_HGx+n of the (x+n)-th scan line HGx+n rises from the low potential Vgl to the high potential Vgh at least partially overlap in time sequence.

Please refer to FIG. 1. The transfer lines VG include an (x−n)-th transfer line VGx−n, an x-th transfer line VGx, and an (x+n)-th transfer line VGx+n, which are respectively electrically connected to the (x−n)-th scan line HGx−n, the x-th scan line HGx, and the (x+n)-th scan line HGx+n. Please refer to FIG. 1 and FIG. 2. The (x−n)-th transfer line VGx−n, the x-th transfer line VGx, and the (x+n)-th transfer line VGx+n respectively have a gate pulse signal S_VGx−n, a gate pulse signal S_VGx, and a gate pulse signal S_VGx+n. The gate pulse signal S_VGx−n of the (x−n)-th transfer line VGx−n, the gate pulse signal S_VGx of the x-th transfer line VGx, and the gate pulse signal S_VGx+n of the (x+n)-th transfer line VGx+n are respectively the same as the gate pulse signal S_HGx−n of the (x−n)-th scan line HGx−n, the gate pulse signal S_HGx of the x-th scan line HGx, and the gate pulse signal S_HGx+n of the (x+n)-th scan line HGx+n.

Please refer to FIG. 1. The pixel columns R include a (k−1)-th pixel column Rk−1, a k-th pixel column Rk, and a (k+1)-th pixel column Rk+1, which are sequentially arranged in the first direction d1, where k is a positive integer greater than or equal to 2; and the data lines DL include a (k−1)-th data line DLk−1, a k-th data line DLk, and a (k+1)-th data line DLk+1, which are respectively electrically connected to the (k−1)-th pixel column Rk−1, the k-th pixel column Rk, and the (k+1)-th pixel column Rk+1.

Please refer to FIG. 1. It is worth noting that in the top view of the pixel array substrate 100, the (x−n)-th transfer line VGx−n is disposed between the (k−1)-th data line DLk−1 and the k-th data line DLk, and the x-th transfer line VGx is disposed between the k-th data line DLk and the (k+1)-th data line DLk+1. In other words, the (x−n)-th transfer line VGx−n and the x-th transfer line VGx are adjacent to the same k-th data line DLk and are respectively located on the left and right sides of the same k-th data line DLk. Please refer to FIG. 1 and FIG. 2. In particular, since the start time tonx of the gate pulse signal S_VGx of the x-th transfer line VGx and the end time toffx−n of the gate pulse signal S_VGx−n of the (x−n)-th transfer line VGx−n overlap in time sequence, the capacitive coupling effect between the (x−n)-th transfer line VGx−n and the k-th data line DLk may offset the capacitive coupling effect between the x-th transfer line VGx and the k-th data line DLk, so that the potential of the pixel electrode 194 (shown in FIG. 3) of the pixel structure PX located in the k-th pixel column Rk and electrically connected to the x-th scan line HGx is not prone to excessive deviation from an ideal value due to the transfer lines VG disposed on the left and right sides thereof. As a result, the pixel structure PX located in the k-th pixel column Rk and electrically connected to the x-th scan line HGx is less prone to abnormal brightness (for example, over-brightness), thereby improving the issue of diagonal bright lines described in the prior art. The following is exemplified in detail with other drawings.

In this embodiment, the 1-st scan line HG1 to the 18-th scan line HG18 are sequentially turned on with a time delay. A time length of the time delay is t (shown in FIG. 6), and a pulse time length of each of the gate pulse signal S_HG1 to the gate pulse signal S_HG18 is Tp (shown in FIG. 6), where n=Tp/t, and n is for example 8, but the disclosure is not limited thereto.

The following is exemplified with FIG. 5 and FIG. 6.

Please refer to FIG. 5 and FIG. 6. In a part of the pixel array substrate 100 of this embodiment, n, x, and k described in the foregoing paragraph may be respectively regarded as 8, 9, and 2 (that is, n=8, x=9, and k=2). Please refer to FIG. 5 and FIG. 6.

In particular, since the start time ton9 of the gate pulse signal S_VG9 of the 9-th transfer line VG9 and the end time toff1 of the gate pulse signal S_VG1 of the 1-st transfer line VG1 overlap in time sequence, the capacitive coupling effect between the 1-st transfer line VG1 and the 2-nd data line DL2 may offset the capacitive coupling effect between the 9-th transfer line VG9 and the 2-nd data line DL2, so that the potential of the pixel electrode 194 (shown in FIG. 3) of the pixel structure PX located in the 2-nd pixel column R2 and electrically connected to the 9-th scan line HG9 is not prone to excessive deviation from the ideal value due to the transfer lines VG disposed on the left and right sides thereof In this way, the pixel structure PX located in the 2-nd pixel column R2 and electrically connected to the 9-th scan line HG9 is not prone to abnormal brightness (for example, over-brightness), thereby improving the issue of diagonal bright lines described in the prior art.

In a part of the pixel array substrate 100 of this embodiment, the scan lines HG include the 1-st scan line HG1 to the 17-th scan line HG17, which are sequentially arranged in the second direction d2, and the end time toff9 of the gate pulse signal S_HG9 of the 9-th scan line HG9 and the start time ton17 of the gate pulse signal S_HG17 of the 17-th scan line HG17 overlap in time sequence; the transfer lines VG further include the 17-th transfer line VG17, which is electrically connected to the 17-th scan line HG17; the pixel columns R further include a 4-th pixel column R4, and the 1-st pixel column R1, the 2-nd pixel column R2, the 3-rd pixel column R3, and the 4-th pixel column R4 are sequentially arranged in the first direction d1; and the data lines DL further include a 4-th data line DL4, which is electrically connected to the 4-th pixel column R4.

Please refer to FIG. 5 and FIG. 6. Similarly, since the end time toff9 of the gate pulse signal S_VG9 of the 9-th transfer line VG9 and the start time ton17 of the gate pulse signal S_VG17 of the 17-th transfer line VG17 overlap in time sequence, the capacitive coupling effect between the 9-th transfer line VG9 and the 3-rd data line DL3 may offset the capacitive coupling effect between the 17-th transfer line VG9 and the 3-rd data line DL3, so that the potential of the pixel electrode 194 (shown in FIG. 3) of the pixel structure PX located in the third pixel column R3 and electrically connected to the 17-th scan line HG17 is not prone to excessive deviation from the ideal value due to the transfer lines VG disposed on the left and right sides thereof. In this way, the pixel structure PX located in the 3-rd pixel column R3 and electrically connected to the 17-th scan line HG17 is not prone to abnormal brightness (for example, over-brightness), thereby improving the issue of diagonal bright lines described in the prior art.

It is worth noting that in the top view of the pixel array substrate 100, the y-th transfer line VGy is disposed between the (q−1)-th data line DLq−1 and the q-th data line DLq, and the (y−n)-th transfer line VGy−n is disposed between the q-th data line DLq and the (q+1)-th data line DLq+1. The following is exemplified with FIG. 5 and FIG. 6.

Please refer to FIG. 5 and FIG. 6. In a part of the pixel array substrate 100 of this embodiment, n, y, and q corresponding to FIG. 11 and FIG. 12 described above may be respectively regarded as 8, 13, and 6 (that is, n=8, y=13, and q=6). Please refer to FIG. 5 and FIG. 6. In a part of the pixel array substrate 100 of this embodiment, the scan lines HG include the 5-th scan line HG5 to the 13-th scan line HG13, which are sequentially arranged in the second direction d2; and a start time ton13 of the gate pulse signal S_HG13 of the 13-th scan line HG13 and an end time toff5 of the gate pulse signal S_HG5 of the 5-th scan line HG5 overlap in time sequence. The transfer lines VG include the 5-th transfer line VG5 and the 13-th transfer line VG13, which are respectively electrically connected to the 5-th scan line HG5 and the 13-th scan line HG13. The 5-th transfer line VG5 and the 13-th transfer line VG13 respectively have the gate pulse signal S_VG5 and the gate pulse signal S_VG13. The gate pulse signal S_VG5 of the 5-th transfer line VG5 and the gate pulse signal S_VG13 of the 13-th transfer line VG13 are respectively the same as the gate pulse signal S_HG5 of the 5-th scan line HG5 and the gate pulse signal S_HG13 of the 13-th scan line HG13. The pixel columns R include the 5-th pixel column R5, the 6-th pixel column R6, the 7-th pixel column R7, and the 8-th pixel column R8, which are sequentially arranged in the first direction d1; and the data lines DL include the 5-th data line DL5, the 6-th data line DL6, the 7-th data line DL7, and the 8-th data line DL8, which are respectively electrically connected to the 5-th pixel column R5, the 6-th pixel column R6, the 7-th pixel column R7, and the 8-th pixel column R8.

Please refer to FIG. 5. It is worth noting that in the top view of the pixel array substrate 100, the 13-th transfer line VG13 is disposed between the 5-th data line DL5 and the 6-th data line DL6, and the 5-th transfer line VG5 is disposed between the 6-th data line DL6 and the 7-th data line DL7. Similarly, the 13-th transfer line VG13 and the 5-th transfer line VG5 are adjacent to the 6-th data line DL6 and are respectively located on the left and right sides of the 6-th data line DL6. Please refer to FIG. 5 and FIG. 6. Similarly, since the end time toff5 of the gate pulse signal S_VG5 of the 5-th transfer line VG5 and the start time ton13 of the gate pulse signal S_VG13 of the 13-th transfer line VG13 overlap in time sequence, the capacitive coupling effect between the 13-th transfer line VG13 and the 6-th data line DL6 may offset the capacitive coupling effect between the 5-th transfer line VG5 and the 6-th data line DL6, so that the potential of the pixel electrode 194 (shown in FIG. 3) of the pixel structure PX located in the 6-th pixel column R6 and electrically connected to the 13-th scan line HG13 is not prone to excessive deviation from the ideal value due to the transfer lines VG disposed on the left and right sides thereof. In this way, the pixel structure PX located in the 6-th pixel column R6 and electrically connected to the 13-th scan line HG13 is not prone to abnormal brightness (for example, over-brightness), thereby improving the issue of diagonal bright lines described in the prior art.

It should be noted that the two transfer lines VG located on the left and right sides of the same data line DL and sequentially arranged in the first direction d1 may offset the capacitance effects of the same data line DL, but the disclosure is not limited thereto. However, the disclosure does not limit that the start time of the gate pulse signal of one of the transfer lines VG arranged first in the first direction d1 must be earlier than the start time of the gate pulse signal of another transfer line VG arranged later. However, the disclosure also does not limit that the start time of the gate pulse signal of one of the transfer lines VG arranged first in the first direction d1 must be later than the start time of the gate pulse signal of another transfer line VG arranged later.

For example, in a part of the pixel array substrate 100 of FIG. 5, the two transfer lines (for example, the 1-st transfer line VG1 and the 9-th transfer line VG9) disposed on the left and right sides of the same data line (for example, the 2-nd data line DL2) and sequentially arranged in the first direction d1 may offset the capacitance effects of the same data line (for example, the 2-nd data line DL2). The start time of the gate pulse signal of one of the transfer lines VG arranged first in the first direction d1 may be earlier than the start time of the gate pulse signal of another transfer line VG arranged later (for example, a start time ton1 of the gate pulse signal S_VG1 of the 1-st transfer line VG1 arranged first in the first direction d1 may be earlier than the start time ton9 of the gate pulse signal S_VG9 of the 9-th transfer line VG9 arranged later). However, in another part of the pixel array substrate 100 of FIG. 5, the transfer lines (for example, the 13-th transfer line VG13 and the 5-th transfer line VG5) disposed on the left and right sides of the same data line (for example, the 6-th data line DL6) and sequentially arranged in the first direction d1 may offset the capacitance effects of the same data line (for example, the 6-th data line DL6). The start time of the gate pulse signal of one of the transfer lines VG arranged first in the first direction d1 may be later than the start time of the gate pulse signal of another transfer line VG arranged later (for example, the start time ton13 of the gate pulse signal S_VG13 of the 13-th transfer line VG13 arranged first in first direction d1 may be later than a start time ton5 of the gate pulse signal S_VG5 of the 5-th transfer line VG5 arranged later).

The following is exemplified with FIG. 5 and FIG. 6.

In a part of the pixel array substrate 100 of this embodiment, n, y, and q corresponding to FIG. 11 and FIG. 12 described above may be respectively regarded as 8, 13, and 6 (that is, n=8, y=13, and q=6).

In particular, p is a positive integer greater than 2, and |y−p| is not equal to n. The following is exemplified with FIG. 5 and FIG. 6.

Please refer to FIG. 5 and FIG. 6. In a part of the pixel array substrate 100 of this embodiment, n, y, q, and p corresponding to FIG. 13 and FIG. 14 described above may be respectively regarded as 8, 15, 9, and 3 (that is, n=8, y=15, q=9, and p=3). Please refer to FIG. 5 and FIG. 6. In the top view of the pixel array substrate 100, the scan lines HG include the 7-th scan line HG7 to the 15-th scan line HG15, which are sequentially arranged in the second direction d2; a start time ton15 of the gate pulse signal S_HG15 of the 15-th scan line HG15 and an end time toff7 of the gate pulse signal S_HG7 of the 7-th scan line HG7 overlap in time sequence; the scan lines HG further include the 3-rd scan line HG3; the transfer lines VG include the 7-th transfer line VG7 and the 15-th transfer line VG15, which are respectively electrically connected to the 7-th scan line HG7 and the 15-th scan line HG15; the transfer lines VG further include the 3-rd transfer line VG3, which is electrically connected to the 3-rd scan line HG3; the pixel columns R include the 8-th pixel column R8, the 9-th pixel column R9, the 10-th pixel column R10, and the 11-th pixel column R11, which are sequentially arranged in the first direction d1; and the data lines DL include the 8-th data line DL8, the 9-th data line DL9, the 10-th data line DL10, and the 11-th data line DL11, which are respectively electrically connected to the 8-th pixel column R8, the 9-th pixel column R9, the 10-th pixel column R10, and the 11-th pixel column R11.

In particular, 3 is a positive integer greater than 2, and |15−3| is not equal to 8.

In other words, in this embodiment, in a part of the pixel array substrate 100, the start times (for example, ton15 and ton7) of the gate pulse signals (for example, S_VG15 and S_VG7) of the two transfer lines VG (for example, the 15-th transfer line VG15 and the 7-th transfer line VG7) located on the left and right sides of the same data line DL (for example, the 9-th data line DL9) may differ by n times the time length t of the time delay (for example, 8t). However, in another part of the pixel array substrate 100, the start times (for example, ton7 and ton3) of the gate pulse signals (for example, S_VG7 and S_VG3) of the transfer lines VG (for example, the 7-th transfer line VG7 and the 3-rd transfer line VG3) located on the left and right sides of the same data line DL (for example, the 10-th data line DL10) may not differ by n times t (for example, differ by 4t).

In the foregoing description, Tp/t=n=8 is taken as an example. However, the disclosure is not limited thereto. In other embodiments, Tp/t=n, and n may also be other positive integers other than 8. The following is exemplified with FIG. 15 and FIG. 16.

FIG. 17 is a schematic cross-sectional view of the pixel structure PX of the pixel array substrate 100 according to an embodiment of the disclosure. FIG. 17 corresponds to a section line of II-II′ FIG. 3.

The specific structure of the pixel structure PX according to an embodiment of the disclosure will be exemplified below with FIG. 3 and FIG. 17. The pixel structure PX may be selectively applied to the pixel array substrate 100 or 100A.

Please refer to FIG. 3 and FIG. 17. In addition to the thin film transistor T and the pixel electrode 194 electrically connected to the thin film transistor T, the pixel structure PX further includes a first common electrode 122. The first common electrode 122 and the pixel electrode 194 partially overlap to form a storage capacitor.

In this embodiment, the pixel structure PX may selectively include a second common electrode 124, which is separated from the first common electrode 122. Please refer to FIG. 3. In the top view of the pixel array substrate 100, the first common electrode 122, the second common electrode 124, and the scan lines HG are arranged in the second direction d2 and are separated from each other.

For example, in this embodiment, the first common electrode 122, the second common electrode 124, and the scan lines HG may belong to the first conductive layer and are separated from each other, the gate Tc of the thin film transistor T may belong to the first conductive layer, and the gate Tc of thin film transistor T and the scan lines HG may be directly connected. The source Ta and the drain Tb of the thin film transistor T may belong to the second conductive layer and are separated from each other, the data lines DL may belong to the second conductive layer, and the data lines DL and the source Ta of the thin film transistor T may be directly connected, but the disclosure is not limited thereto.

Please refer to FIG. 3 and FIG. 17. The pixel structure PX further includes a conductive pattern 142, which is electrically connected to the thin film transistor T. Specifically, the conductive pattern 142 is electrically connected to the drain Tb of the thin film transistor T. For example, in this embodiment, the conductive pattern 142 and the drain Tb of the thin film transistor T may belong to the same second conductive layer and may be directly connected, but the disclosure is not limited thereto.

The conductive pattern 142 has a first portion 142-1, which is disposed on the first common electrode 122. Specifically, the conductive pattern 142 is disposed on the insulating layer 130, and the first portion 142-1 of the conductive pattern 142 and the first common electrode 122 overlap. In this embodiment, the conductive pattern 142 further has a second portion 142-2, which is disposed on the second common electrode 124. Specifically, the conductive pattern 142 is disposed on the insulating layer 130, and the second portion 142-2 of the conductive pattern 142 and the second common electrode 124 overlap. In this embodiment, the conductive pattern 142 further has a third portion 142-3, which is connected between the first portion 142-1 and the second portion 142-2. In the top view of the pixel array substrate 100, the third portion 142-3 of the conductive pattern 142 is located between the first common electrode 122 and the second common electrode 124, and does not overlap with the first common electrode 122 and the second common electrode 124.

Please refer to FIG. 3 and FIG. 17, the pixel structure PX further includes a first insulating layer 150, which is disposed on the conductive pattern 142 and has an opening 152 overlapping with the conductive pattern 142. In this embodiment, the opening 152 of the first insulating layer 150 may overlap with the third portion 142-3 of the conductive pattern 142. For example, in this embodiment, the material of the first insulating layer 150 may be an inorganic material (for example, silicon oxide, silicon nitride, silicon oxynitride, or a stacked layer of at least two of the foregoing materials), an organic material, or a combination of the foregoing materials.

Please refer to FIG. 3 and FIG. 17. The pixel structure PX further includes a color filter pattern 160, which is disposed on the first insulating layer 150 and has an opening 162 overlapping with the conductive pattern 142. Please refer to FIG. 3. For example, in the top view of the pixel array substrate 100, the opening 152 of the first insulating layer 150 may be located within the opening 162 of the color filter pattern 160.

Please refer to FIG. 3 and FIG. 17. The pixel structure PX further includes a second insulating layer 170, which is disposed on the color filter pattern 160 and has an opening 172 overlapping with the conductive pattern 142. For example, in this embodiment, the material of the second insulating layer 170 may be an inorganic material (for example, silicon oxide, silicon nitride, silicon oxynitride, or a stacked layer of at least two of the foregoing materials), an organic material, or a combination of the foregoing materials.

In this embodiment, the pixel array substrate 100 may selectively include a transparent conductive layer 180, which is disposed on the second insulating layer 170. The transparent conductive layer 180 is disposed between the film layer to which the transfer lines VG belong and the film layer to which the pixel electrode 194 belongs to shield the pixel electrode 194, so that the potential of the pixel electrode 194 is not easily affected by the transfer lines VG. For example, in this embodiment, the material of the transparent conductive layer 180 may include metal oxides, such as indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, other suitable oxides, or stacked layers of at least two of the foregoing, but the disclosure is not limited thereto.

The pixel electrode 194 is disposed on the second insulating layer 170 and is electrically connected to the conductive pattern 142 through the opening 152 of the first insulating layer 150 and the opening 172 of the second insulating layer 170. For example, in this embodiment, the pixel structure PX may selectively include a third insulating layer 190, which is disposed on the second insulating layer 170 and covers the transparent conductive layer 180. The third insulating layer 190 has an opening 192, which overlaps with the conductive pattern 142. The pixel electrode 194 may be disposed on the third insulating layer 190 and electrically contact the third portion 142-3 of the conductive pattern 142 through the opening 192 of the third insulating layer 190, the opening 172 of the second insulating layer 170, and the opening 152 of the first insulating layer 150, but the disclosure is not limited thereto.

In this embodiment, the opening 192 of the third insulating layer 190, the opening 172 of the second insulating layer 170, and the opening 152 of the first insulating layer 150 may be located on the third portion 142-3 of the conductive pattern 142. The opening 192 of the third insulating layer 190, the opening 172 of the second insulating layer 170, and the opening 152 of the first insulating layer 150 may be substantially aligned, but the disclosure is not limited thereto.

In this embodiment, in the top view of the pixel array substrate 100, the opening 152 of the first insulating layer 150 and the opening 172 of the second insulating layer 170 may be located between the first common electrode 122 and the second common electrode 124 and do not overlap with the first common electrode 122 and the second common electrode 124.

Please refer to FIG. 3. It is worth noting that in the top view of the pixel array substrate 100, the first portion 142-1 of the conductive pattern 142 covers all edges 122e of the first common electrode 122 located within the opening 162 of the color filter pattern 160. Please refer to FIG. 3 and FIG. 17. In other words, within the opening 162 of the color filter pattern 160, there is no overlap or intersection between edges 142e of the conductive pattern 142 and the edges 122e of the first common electrode 122, and the first common electrode 122, the conductive pattern 142, and the insulating layer 130 sandwiched therebetween cannot easily form a stacked structure with steep sidewalls. Near the edges 122e of the first common electrode 122, the second insulating layer 170 does not need to be formed on a stacked structure with steep sidewalls and can be well disposed on the first insulating layer 150. As such, the second insulating layer 170 can well cover the color filter pattern 160 and a sidewall 164 thereof, so that the gas within the color filter pattern 160 cannot easily pass through the second insulating layer 170 to be leaked out of the pixel array substrate 100, which causes the issue of bubbles in a display panel.

Please refer to FIG. 3. In this embodiment, in the top view of the pixel array substrate 100, the second portion 142-2 of the conductive pattern 142 covers all edges 124e of the second common electrode 124 located within the opening 162 of the color filter pattern 160. Please refer to FIG. 3 and FIG. 17. In other words, in the opening 162 of the color filter pattern 160, there is no overlap or intersection between the edges 142e of the conductive pattern 142 and the edges 124e of the second common electrode 124, and the second common electrode 124, the conductive pattern 142, and the insulating layer 130 sandwiched therebetween cannot easily form a stacked structure with steep sidewalls. Near the edges 124e of the second common electrode 124, the second insulating layer 170 does not need to be formed on a stacked structure with steep sidewalls and can be well disposed on the first insulating layer 150. As such, the second insulating layer 170 can well cover the color filter pattern 160 and the sidewall 164 thereof, so that the gas within the color filter pattern 160 cannot easily pass through the second insulating layer 170 to be leaked out of the pixel array substrate 100, which causes the issue of bubbles in the display panel.

FIG. 18 is a schematic top view of a layout of a pixel structure PX of a pixel array substrate 100B according to an embodiment of the disclosure.

FIG. 19 is a schematic cross-sectional view of the pixel structure PX of the pixel array substrate 100B according to an embodiment of the disclosure. FIG. 19 corresponds to a section line III-III′ of FIG. 18.

The pixel structure PX of FIG. 18 and FIG. 19 may also be selectively applied to the pixel array substrate 100 or 100A.

The pixel structure PX of FIG. 18 and FIG. 19 is similar to the pixel structure PX of FIG. 3 and FIG. 17, so the same or similar elements are indicated by the same or similar reference numerals.
