Abstract

A display panel includes: a transmissive area surrounded by a display area; first and second data lines each including a first part and a second part that are apart from each other with the transmissive area therebetween; first and second bridge lines in the display area and disposed opposite sides of the transmissive area, the first bridge line electrically connecting the first part and the second part of the first data line to each other, the second bridge line electrically connecting the first part and the second part of the second data line to each other; first and second vertical conductive lines in the display area; a first horizontal conductive line electrically connected to the first vertical conductive line; and a second horizontal conductive line electrically connected to the second vertical conductive line.

First claim

What is claimed is:

1 . A display panel, comprising:
a transmissive area; a display area surrounding the transmissive area; a plurality of data lines extending in a first direction, wherein the plurality of data lines comprise:
a first data line including a first part and a second part, wherein the first part and the second part of the first data line each extend in a first direction in the display area and are apart from each other with the transmissive area therebetween; and
a second data line including a first part and a second part, wherein the first part and the second part of the second data line each extend in the first direction in the display area and are apart from each other with the transmissive area therebetween,
a first bridge line electrically connecting the first part of the first data line to the second part of the first data line, wherein the first bridge line comprises:
a first sub-bridge part extending in a second direction crossing the first direction in the display area, and connected to the second part of the first data line via a first contact hole;
a second sub-bridge part connected to the first sub-bridge part via a second contact hole; and
a third sub-bridge part connected to the second sub-bridge part and the first part of the first data line, and
a second bridge line electrically connecting the first part of the second data line to the second part of the second data line, wherein the second bridge line comprises:
a fourth sub-bridge part extending in the second direction in the display area, and connected to the second part of the second data line via a third contact hole;
a fifth sub-bridge part connected to the fourth sub-bridge part via a fourth contact hole; and
a sixth sub-bridge part connected to the fifth sub-bridge part and the first part of the second data line,
wherein: the first and second data lines are disposed at a first side of a central axis that passes through a center of the transmissive area in the first direction, the first data line is closest to the central axis at the first side of the central axis, and a first distance between the first and second contact holes is greater than a second distance between the third and fourth contact holes.

2 . The display panel of claim 1 , wherein:
the first contact hole and the third contact hole are arranged along a first oblique direction crossing the first and second directions, and the second contact hole and the fourth contact hole are arranged in a second oblique direction crossing the first and second directions and the first oblique direction.

3 . The display panel of claim 1 , wherein:
a length of the first sub-bridge part is greater than a length of the fourth sub-bridge part.

4 . The display panel of claim 1 , wherein:
the first sub-bridge part and the second sub-bridge part are disposed on different layers, and the fourth sub-bridge part and the fifth sub-bridge part are disposed on different layers.

5 . The display panel of claim 4 , wherein:
the first sub-bridge part and the fourth sub-bridge part are disposed on a same layer, the second sub-bridge part and the fifth sub-bridge part are disposed on a same layer, and, the third sub-bridge part and sixth sub-bridge part are disposed on a same layer.

6 . The display panel of claim 1 , wherein:
at least one of the plurality of data lines overlaps and crosses the first sub-bridge part of the first bridge line.

7 . The display panel of claim 1 , wherein the plurality of data lines further comprises:
a third data line including a first part and a second part, wherein the first part and the second part of the third data line each extend in the first direction in the display area and are apart from each other with the transmissive area therebetween; and a fourth data line including a first part and a second part, wherein the first part and the second part of the fourth data line each extend in the first direction in the display area and are apart from each other with the transmissive area therebetween,
wherein:
the first part and the second part of the third data line are electrically connected to a third bridge line, and the first part and the second part of the fourth data line are electrically connected to a fourth bridge line, and
the third and fourth data lines are disposed at a second side of the central axis of the transmissive area, the second side is opposite to the first side of the central axis, and the third data line is closest to the central axis at the second side of the central axis.

8 . The display panel of claim 7 , wherein:
the third bridge line comprises:
a seventh sub-bridge part extending in the second direction in the display area, and connected to the second part of the third data line via a fifth contact hole;
an eighth sub-bridge part connected to the seventh sub-bridge part via a sixth contact hole; and
a ninth sub-bridge part connected to the eight sub-bridge part and the first part of the third data line, and
the fourth bridge line comprises:
a tenth sub-bridge part extending in the second direction in the display area, and connected to the second part of the fourth data line via a seventh contact hole;
an eleventh sub-bridge part connected to the tenth sub-bridge part via an eighth contact hole; and
a twelfth sub-bridge part connected to the eleventh sub-bridge part and the first part of the fourth data line,

wherein a third distance between the fifth and sixth contact holes is greater than a fourth distance between the seventh and eight contact holes.

9 . The display panel of claim 8 , wherein:
the fifth contact hole and the seventh contact hole are arranged along a third oblique direction crossing the first and second directions, and the sixth contact hole and the eighth contact hole are arranged in a fourth oblique direction crossing the first and second directions and the third oblique direction.

10 . The display panel of claim 8 , wherein:
at least one of the plurality of data lines overlaps and crosses the seventh sub-bridge part of the third bridge line.

11 . The display panel of claim 8 , wherein:
the seventh sub-bridge part and the eighth sub-bridge part are disposed on different layers, and the fourth sub-bridge part and the fifth sub-bridge part are disposed on different layers.
