The display panel DP includes the data driver DDV, the data line DL, a connection electrode CE, the pad portion PD, a first scan line SL1, a second scan line SL2, a third scan line SL3, and a fourth scan line SL4, the first scan driver SD1, the second scan driver SD2, a third scan driver SD3, and a fourth scan drivers SD4.
The data driver DDV and the pad portion PD may be disposed in the pad area PA. The data line DL may be electrically connected to the data driver DDV. The data line DL may receive the data voltage from the data driver DDV and apply the data voltage to the pixel PX. The pad portion PD may provide the first power voltage (e.g., the first power voltage ELVDD of
The data line DL may be disposed on the display area DA. The data line may be disposed parallel to the second direction DR2 in the display area DA.
The data line DL may extend from the data driver DDV in a direction opposite to the second direction DR2. A plurality of data lines DL may be arranged. The plurality of data lines DL may be spaced apart from each other in the first direction DR1. The data line DL may apply a data signal transmitted from the data driver DDV to the pixel PX.
The data line DL located around the hole area HA may be disconnected by the hole area HA. Specifically, the data line DL extending from the data driver DDV may be disconnected at a point in the display area DA adjacent to the hole area HA in the second direction DR2. In addition, the data line DL extending from one side of the display area DA opposite to the data driver DDV in the second direction DR2 may be disconnected at a point in the display area DA adjacent to the hole area in the direction opposite to the second direction DR2.
The data line DL may be disposed on the first via insulation layer (e.g., the first via insulation layer VIA1 of
The connection electrode CE may be disposed in the display area DA around the hole area HA. That is, the connection electrode CE may not be disposed in the hole area HA. The connection electrode CE may be electrically connected to a disconnected data line DL passing around the hole area HA. The connection electrode CE may bypass around the hole area HA. For example, the connection electrode CE may have a rectangular planar shape that bypasses the hole area HA. However, the present disclosure may not be limited to this.
The connection electrode CE may electrically connect the data line DL that is disconnected by the hole area HA. The connection electrode CE may contact each of a disconnected data line DL in the display area DA adjacent to the hole area HA in the second direction DR2 and a disconnected data line DL in the display area DA adjacent to the hole area HA in the direction opposite to the second direction DR2. Accordingly, the connection electrode CE may connect the disconnected data line DL and apply the data signal to the pixel PX disposed in the display area DA around the hole area HA.
The first, second, third, and fourth scan drivers SD1, SD2, SD3, and SD4 may be disposed in the non-display area NDA. For example, the first scan driver SD1 may be adjacent to one side, e.g., a first side, of the display area DA, and be disposed in the non-display area NDA. The second scan driver SD2 may be adjacent to an other side, e.g., a second side, opposite to the first side in the first direction DR1 of the display area DA, and be disposed in the non-display area NDA. The third scan driver SD3 may be adjacent to the one side, e.g., the first side, of the display area DA, and be disposed in the non-display area NDA. The fourth scan driver SD4 may be adjacent to the other side, e.g., the second side, of the display area DA, and be disposed in the non-display area NDA. However, the present disclosure may not be limited to this, and the first, second, third, and fourth scan drivers SD1, SD2, SD3, and SD4 may be disposed in the display area DA.
Different scan signals may be applied to the first, second, third, and fourth scan drivers SD1, SD2, SD3, and SD4. For example, the first gate initialization signal GI may be applied to the first scan driver SD1. The gate compensate signal GC may be applied to the second scan driver SD2. The second gate initialization signal GB may be applied to the third scan driver SD3. The light emission control signal EM may be applied to the fourth scan driver SD4. However, the present disclosure may not be limited to this, one scan signal selected among the first gate initialization signal GI, the gate compensate signal GC, the second gate initialization signal GB, and the light emission control signal EM may be applied to each of the first, second, third, and fourth scan drivers SD1, SD2, SD3, and SD4. In this case, a same signal may not be applied two different scan drivers among the first, second, third, and fourth scan drivers SD1, SD2, SD3, and SD4.
Each of the first, second, third, and fourth scan drivers SD1, SD2, SD3, and SD4 may be a one-side driving scan driver driven which is disposed in one side of the display device (e.g., the display device DD). That is, the first, second, third, and fourth scan drivers SD1, SD2, SD3, and SD4 may not be a scan driver driven on two side which is disposed in two sides of the display device.
However, the one-side driving scan driver may be defined as a scan driver which drives in such a way that a same signal as a scan signal (e.g., the first gate initialization signal GI, the gate compensate signal GC, the second gate initialization signal GB, and the light emission control signal EM) applied to the scan driver disposed on the one side of the display device is not applied to the driver disposed on the other side opposite to the one side. That is, the one-side driving may be referred as a driving in a manner in which one type of scan signal is applied to only one scan driver among a scan driver disposed on the one side of the display device and a scan driver disposed on the another side.
Unlike the one-side driving, a both-side driving may mean a driving in which same signal as the scan signal applied to the scan driver disposed on the one side of the display device is applied to the scan driver disposed on the other side. That is, the both-side driving may mean a method in which one type of scan signal is simultaneously applied to a scan driver disposed on the one side of the display device and a scan driver disposed on the other side.
A first scan line SL1, a second scan line SL2, a third scan line SL3, and a fourth scan line SL4 may be disposed in the display area DA. The first, second, third, and fourth scan lines SL1, SL2, SL3, and SL4 may be disposed parallel to the first direction DR1 in the display area DA.
The first scan line SL1 may be electrically connected to the first scan driver SD1. Accordingly, the first scan line SL1 may apply the scan signal applied to the first scan driver SD1 to the pixel PX. For example, the first scan line SL1 may apply the first gate initialization signal GI to the pixel PX.
The first scan line SL1 may extend in a direction opposite to the first direction DR1 from a portion connected to the first scan driver SD1 and may be disconnected in an area adjacent to the second scan driver SD2.
The second scan line SL2 may be electrically connected to the second scan driver SD2. Accordingly, the second scan line SL2 may apply the scan signal applied to the second scan driver SD2 to the pixel PX. For example, the second scan line SL2 may apply the gate compensation signal GC to the pixel PX.
The second scan line SL2 may extend in the first direction DR1 from a portion connected to the second scan driver SD2 and may be disconnected in an area adjacent to the first scan driver SD1.
The third scan line SL3 may be electrically connected to the third scan driver SD3. Accordingly, the third scan line SL3 may apply the scan signal applied to the third scan driver SD3 to the pixel PX. For example, the third scan line SL3 may apply the second gate initialization signal GB to the pixel PX.
The third scan line SL3 may extend in the direction opposite to the first direction DR1 from a portion connected to the third scan driver SD3 and may be disconnected at an area adjacent to the second scan driver SD2 and the fourth scan driver SD4.
The fourth scan line SL4 may be electrically connected to the fourth scan driver SD4. Accordingly, the fourth scan line SL4 may apply the scan signal applied to the fourth scan driver SD4 to the pixel PX. For example, the fourth scan line SL4 may apply the light emission control signal EM to the pixel PX.
The fourth scan line SLA extends in the first direction DR1 from a portion connected to the fourth scan driver SD4 and may be disconnected in an area adjacent to the first scan driver SD1 and the third scan driver SD3.

Each of the first, second, third, and fourth scan lines SL1, SL2, SL3, SL4 may be spaced apart from each other in a plan view. Each of the first, second, third, and fourth straight lines SLW1, SLW2, SLW3, SLW4 may be spaced apart from each other in a second direction DR2. Each of the first, second, third, and fourth bypass lines SBW1, SBW2, SBW3, and SBW4 may be spaced apart from each other in a direction away from a center of the hole MH.
In an embodiment, each of the first, second, third, and fourth straight lines SLW1, SLW2, SLW3, SLW4 may be arranged alternatively in the second direction DR2.

In an embodiment, each of the first, second, third, and fourth bypass lines SBW1, SBW2, SBW3, and SBW4 may be arranged alternatively along the direction away from the center of the hole MH.

In an embodiment, an average distance from the center of the hole MH to the first, second, third, and fourth bypass lines SBW1, SBW2, SBW3, and SBW4 may be smaller than an average distance from the center of the hole MH to the connection electrode CE. Specifically, the first, second, third, and fourth bypass lines SBW1, SBW2, SBW3, and SBW4 may be arranged along the boundary of the hole area HA, and may be adjacent to the boundary of the hole area HA. However, an average distance from the boundary of the hole MH to the connection CE may be relatively larger than an average distance from the boundary of the hole MH to the first, second, third, and the fourth bypass lines SBW1, SBW2, SBW3, and SBW4.
