Abstract

A display apparatus includes a substrate including a display area and a peripheral area outside the display area, a common voltage supply line arranged in the peripheral area and including a first common voltage input part, a second common voltage input part, and a third common voltage input part between the first and second voltage input parts each arranged in a first edge of the display area, a first common voltage line extending from the third common voltage input part and crossing the display area in a first direction, a first data line extending in the first direction across the display area, a first data input line arranged in the peripheral area, and a first connection line connecting the first data input line to the first data line.

First claim

What is claimed is:

1 . A display apparatus comprising:
a substrate including a display area and a peripheral area outside the display area; a common voltage supply line arranged in the peripheral area and including a first common voltage input part, a second common voltage input part, and a third common voltage input part each arranged in a first edge of the display area; a first common voltage line extending from the third common voltage input part into the display area in a first direction, the third common voltage input part being between the first common voltage input part and the second common voltage input part, wherein the first common voltage line is electrically connected to a first horizontal common voltage line extending in a second direction crossing the first direction; a first data line extending in the first direction across the display area and arranged on one side of a virtual line extending in the first direction through the third common voltage input part; a first data input line arranged in the peripheral area; and a first connection line arranged in the display area and configured to connect the first data input line to the first data line, wherein the first connection line includes a vertical connector and a horizontal connector, the vertical connector extending in the first direction, and the horizontal connector crossing the vertical connector and wherein one end of the first horizontal common voltage line is adjacent to a connection region between the vertical connector and the horizontal connector.

2 . The display apparatus of claim 1 , wherein the first common voltage line and the first horizontal common voltage line are arranged on different layers.

3 . The display apparatus of claim 1 , wherein the first horizontal common voltage line and the horizontal connector are arranged on a same layer.

4 . The display apparatus of claim 1 , further comprising a second horizontal common voltage line arranged in the display area, arranged far away from the first edge of the display area, and electrically connected to the first common voltage line,
wherein a length of the first horizontal common voltage line is less than a length of the second horizontal common voltage line.

5 . A display apparatus comprising:
a substrate including a display area and a peripheral area outside the display area; a common voltage supply line arranged in the peripheral area and including a first common voltage input part, a second common voltage input part, and a third common voltage input part each arranged in a first edge of the display area; a first common voltage line extending from the third common voltage input part into the display area in a first direction, the third common voltage input part being between the first common voltage input part and the second common voltage input part, wherein the first common voltage line is electrically connected to a first horizontal common voltage line extending in a second direction crossing the first direction; a first data line extending in the first direction across the display area and arranged on one side of a virtual line extending in the first direction through the third common voltage input part; a first data input line arranged in the peripheral area; a first connection line arranged in the display area and configured to connect the first data input line to the first data line; a second common voltage line extending in the first direction from the first common voltage input part; and a third common voltage line arranged between the first common voltage line and the second common voltage line and having a length different from a length of the first common voltage line or a length of the second common voltage line.

6 . The display apparatus of claim 5 , wherein the first connection line includes a vertical connector and a horizontal connector, the vertical connector extending in the first direction, and the horizontal connector crossing the vertical connector, and
one end of the third common voltage line is adjacent to the vertical connector.

7 . The display apparatus of claim 5 , wherein one end of the third common voltage line is adjacent to an end of the first horizontal common voltage line.

8 . A display apparatus comprising:
a substrate including a display area and a peripheral area outside the display area; a common voltage supply line arranged in the peripheral area and including a first common voltage input part, a second common voltage input part, and a third common voltage input part each arranged in a first edge of the display area; a first common voltage line extending from the third common voltage input part into the display area in a first direction, the third common voltage input part being between the first common voltage input part and the second common voltage input part; a first horizontal common voltage line and a second horizontal common voltage line extending in a second direction crossing the first direction and electrically connected to the first common voltage line; a first data line extending in the first direction across the display area and arranged on one side of a virtual line extending in the first direction through the third common voltage input part; a first data input line arranged in the peripheral area; and a first connection line arranged in the display area and connecting the first data input line to the first data line.

9 . The display apparatus of claim 8 , wherein the first horizontal common voltage line and the second horizontal common voltage line are each arranged on a layer different from a layer on which the first common voltage line is arranged.

10 . The display apparatus of claim 9 , wherein a connection region between the first horizontal common voltage line and the first common voltage line and a connection region between the second horizontal common voltage line and the first common voltage line are arranged in the display area.

11 . The display apparatus of claim 8 , wherein the first horizontal common voltage line is relatively adjacent to the first edge of the display area, and the second horizontal common voltage line is relatively away from the first edge of the display area, and
wherein a length of the second horizontal common voltage line in the second direction is greater than a length of the first horizontal common voltage line in the first direction.

12 . The display apparatus of claim 11 , wherein the first connection line includes a vertical connector and a horizontal connector, the vertical connector extending in the first direction, and the horizontal connector crossing the vertical connector, and
wherein one end of the first horizontal common voltage line is adjacent to a connection region between the vertical connector and the horizontal connector.

13 . The display apparatus of claim 12 , further comprising a first separated horizontal common voltage line arranged opposite the first horizontal common voltage line with the horizontal connector therebetween.

14 . The display apparatus of claim 12 , wherein the first horizontal common voltage line and the horizontal connector are arranged on a same layer.

15 . The display apparatus of claim 8 , further comprising:
a second common voltage line extending in the first direction from the first common voltage input part; and a third common voltage line arranged between the first common voltage line and the second common voltage line and having a length different from a length of the first common voltage line or a length of the second common voltage line.
