The display panel of the present invention is a thin film transistor liquid crystal display.
Refer to
The display panel of the present invention has a first display area 105, a second display area 104, and a non-display area 106. The non-display area 106 is disposed between the first display area 105 and the second display area 104. The first display area 105 and the second display area 104 correspond to the pixel electrodes of the display panel, and the non-display area 106 corresponds to data lines and scan lines of the display panel.
The display panel has a first panel 101, a second panel 102 and a liquid crystal layer 103. The first panel 101 is overlapped on the second panel 102 to form a liquid crystal cell, and the liquid crystal layer 103 is disposed in the liquid crystal cell between the first panel 101 and the second panel 102.
The first panel 101 comprises a first base 1011, an element arrayed layer 1012, a color film, and a first light shielding layer. The element arrayed layer 1012 is disposed on the first base 1011, and the element arrayed layer 1012 has thin film transistor switches, data lines, scan lines, and pixel electrodes. The color film is disposed on the element arrayed layer 1012, and the color film has a first color barrier 1013 and a second color barrier 1015. The first color barrier 1013 corresponds to the first display area 105, and the second color barrier 1015 corresponds to the second display area 104. The first light shielding layer is disposed on the element arrayed layer 1012. The first light shielding layer has a first light shielding block 1017, and the first light shielding block 1017 corresponds to the non-display area 106.
The second panel 102 comprises a second base 1021 and a second light shielding layer. The second light shielding layer has a second light shielding block 1022, and the second light shielding block 1022 corresponds to the non-display area 106.
In the embodiment, the first color barrier 1013 is a color barrier of the red, green or blue colored barriers, and the second color barrier 1015 is another color barrier of the red, green, or blue colored barriers.
The first color barrier 1013 has a first extending portion 1014, and the second color barrier 1015 has a second extending portion 1016. The first extending portion 1014 and the second extending portion 1016 are disposed in the non-display area 106.
The first light shielding block 1017 is formed by stacking the first extending portion 1014 and the second extending portion 1016.
In the embodiment, there are three kinds of the thickness of the first extending portion 1017, and the first extending portion 1017 is also formed in three types.
Type 1:
A thickness of the first extending portion 1014 is less than a thickness of the first color barrier 1013. The first extending portion 1014 is formed by implementing a first mask process on a first color barrier material layer 301. The first color barrier material layer 301 corresponds to the first color barrier 1013 in the first display area 105.
At this time, a thickness of the second extending portion 1016 is not implemented a reducing thickness process, thus the thickness of the second extending portion 1016 is equal to a thickness of a second color barrier material layer 601 in the non-display area 106. A thickness of the first light shielding block 1017 is equal to the sum of the thickness of the first extending portion 1014 and the thickness of the second color barrier material layer 601 in the non-display area 106.
Type 2:
A thickness of the second extending portion 1016 is less than a thickness of the second color barrier 1015. The second extending portion 1016 is formed by implementing a second mask process on the second color barrier material layer 601. The second color barrier material layer 601 corresponds to the second color barrier 1015 in the second display area 104.
In this embodiment, a thickness of the first extending portion 1014 is not implemented in a reducing thickness process, thus the thickness of the first extending portion 1014 is equal to a thickness of the first color barrier material layer 301 in the non-display area 106. A thickness of the first light shielding block 1017 is equal to the sum of the thickness of the second extending portion 1016 and the thickness of the first color barrier material layer 301 in the non-display area 106.
Type 3:
The thickness of the first extending portion 1014 is less than the thickness of the first color barrier 1013, and the thickness of the second extending portion 1016 is less than the thickness of the second color barrier 1015.
The first extending portion 1014 is formed by implementing the first mask process on the first color barrier material layer 301. The first color barrier material layer 301 corresponds to the first color barrier 1013 in the first display area 105.
The second extending portion 1016 is formed by implementing the second mask process on the second color barrier material layer 601. The second color barrier material layer 601 corresponds to the second color barrier 1015 in the second display area 104.
Refer to
In the embodiment, the mask 401, 701 of the first and the second mask processes are the first mask 901 and the second mask 1001, respectively.
Refer to
Refer to
The first mask 901 and the second mask 1001 are preferably one of the half tone mask or the gray tone mask.
In the embodiment, the second light shielding block 1022 is a black photo spacer, and the second light shielding block 1022 connects to the first light shielding block 1017.
The first panel 101 and second panel 102 are spaced from the second light shielding block 1022 and the first light shielding block 1017, and the second light shielding block 1022 and the first light shielding block 1017 are shielded from a through light. The through light is emitted from the first display area 105 to the second display area 104, or emitted from the second display area 104 to the first display area 105.
In the embodiment, the first extending portion 1014 of the first color barrier 1013 and the second extending portion 1016 of the second color barrier 1015 are overlapped to form the first light shielding block 1017. The first color barrier 1013 and the second color barrier 1015 are any two color barriers of the red, green, or blue colored barriers. Thus the first light shielding block 1017 is shielded from the light. Furthermore, the thickness of the first color barrier 1013 and the thickness of the second color barrier 1015 are reduced at the non-display area 106, and the thickness of the first extending portion 1014 and/or the second extending portion 1016 are reduced. Thus, the sum of the thickness of the first extending portion 1014 and the thickness of the second extending portion 1016 is less than the sum of the thickness of the first color barrier material layer 301 and the thickness of the second color barrier material layer 601. When an interval is kept between the first panel 101 and the second panel 102, the thickness of the first light shielding block 1017 is reduced and the thickness of the second light shielding block 1022 is increased. In other words, the liquid crystal cell has enough space to receive the second light shielding block 1022 without a planarization layer. The shading effect of the first light shielding block 1017 and the second light shielding block 1022 can be increased (the shading effect is worse by thinning the thickness of the second light shielding block 1022). Therefore, the present invention can prevent the light leakage of the display panel.
The first light shielding block 1017 is implemented to shield the light, and the active principle is described as follows:
When the first color barrier 1013 is a red colored barrier, and the second color barrier 1015 is a blue colored barrier. The first extending portion 1014 is formed from a red colored resistive material, and the second extending portion 1016 is formed from a blue colored resistive material. The light is emitted to the first extending portion 1014 (red colored resistive material), and a red light penetrates the the first extending portion 1014, and a blue light and a green light are absorbed by the first extending portion 1014. The red light is emitted to the second extending portion 1016 (blue colored resistive material) from the first extending portion 1014, and the red light is absorbed by the second extending portion 1016. In other words, the light can be absorbed (shielded) by combining the first extending portion 1014 and the second extending portion 1016. Therefore, the present invention can prevent the light leakage problem of the display panel.

The first color barrier material layer 301 corresponds to the first color barrier 1013 in the first display area 105.
In this embodiment, a thickness of the second extending portion 1016 is not implemented in a reducing thickness process, thus the thickness of the second extending portion 1016 is equal to a thickness of a second color barrier material layer 601 in the non-display area 106. A thickness of the first light shielding block 1017 is equal to the sum of the thickness of the first extending portion 1014 and the thickness of the second color barrier material layer 601 in the non-display area 106.
Type 2:
A thickness of the second extending portion 1016 is less than a thickness of the second color barrier 1015.
In this case, the sub-steps are explained as follows:
In the steps 1303 and 1304, forming a second color barrier material layer 601 on the element arrayed layer 1012, and implementing a second mask process on the second color barrier material layer 601 located in the non-display area 106 to form the second extending portion 1016, wherein the second color barrier material layer 601 covers the second display area 104 and the non-display area 106, and the second color barrier material layer 601 corresponds to the second color barrier 1015 in the second display area 104.
In this embodiment, a thickness of the first extending portion 1014 is not implemented in a reducing thickness process, thus the thickness of the first extending portion 1014 is equal to a thickness of the first color barrier material layer 301 in the non-display area 106. A thickness of the first light shielding block 1017 is equal to the sum of the thickness of the second extending portion 1016 and the thickness of the first color barrier material layer 301 in the non-display area 106.
Type 3:
The thickness of the first extending portion 1014 is less than the thickness of the first color barrier 1013, and the thickness of the second extending portion 1016 is less than the thickness of the second color barrier 1015.
In this case, the sub-steps are explained as follows:
In the steps 1301 and 1302, forming a first color barrier material layer 301 on the element arrayed layer 1012, and implementing a first mask process on the first color barrier material layer located in the non-display area 106 to form the first extending portion 1014, wherein the first color barrier material layer 301 covers the first display area 105 and the non-display area 106. The first color barrier material layer 301 corresponds to the first color barrier 1013 in the first display area 105.
In the steps 1303 and 1304, forming a second color barrier material layer 601 on the element arrayed layer 1012, and implementing a second mask process on the second color barrier material layer 601 located in the non-display area 106 to form the second extending portion 1016, wherein the second color barrier material layer 601 covers the second display area 104 and the non-display area 106, and the second color barrier material layer 601 corresponds to the second color barrier 1015 in the second display area 104.
Refer to
In the embodiment, the mask 401, 701 of the first and the second mask processes are the first mask 901 and the second mask 1001, respectively.
Refer to
Refer to
The first mask 901 and the second mask 1001 are preferably one of the half tone mask or the gray tone mask.
In the embodiment, the first extending portion 1014 of the first color barrier 1013 and the second extending portion 1016 of the second color barrier 1015 are overlapped to form the first light shielding block 1017. The first color barrier 1013 and the second color barrier 1015 are any two color barriers of the red, green, or blue colored barriers. Thus the first light shielding block 1017 is shielded from the light. Furthermore, the thickness of the first color barrier 1013 and the thickness of the second color barrier 1015 are reduced in the non-display area 106, and the thickness of the first extending portion 1014 and/or the second extending portion 1016 are reduced. Thus, the sum of the thickness of the first extending portion 1014 and the thickness of the second extending portion 1016 is less than the sum of the thickness of the first color barrier material layer 301 and the thickness of the second color barrier material layer 601. When an interval is kept between the first panel 101 and the second panel 102, the thickness of the first light shielding block 1017 is reduced and the thickness of the second light shielding block 1022 is increased. In other words, the liquid crystal cell has an enough space to receive the second light shielding block 1022 without a planarization layer. The shading effect of the first light shielding block 1017 and the second light shielding block 1022 can be increased (the shading effect is made worse by decreasing the thickness of the second light shielding block 1022).
The first light shielding block 1017 is implemented to shield the light, and the active principle is described as follows:
When the first color barrier 1013 is a red colored barrier and the second color barrier 1015 is a blue colored barrier, the first extending portion 1014 is formed from a red colored resistive material, and the second extending portion 1016 is formed from a blue colored resistive material. The light is emitted to the first extending portion 1014 (red colored resistive material), and a red light penetrates the the first extending portion 1014, and a blue light and a green light is absorbed by the first extending portion 1014. The red light is emitted to the second extending portion 1016 (blue colored resistive material) from the first extending portion 1014, and the red light is absorbed by the second extending portion 1016. In other words, the light can be absorbed (shielded) by combining the first extending portion 1014 and the second extending portion 1016. Therefore, the present invention can prevent the light leakage of the display panel.
