Abstract

A display device is disclosed. The display device includes a substrate having an active area including a plurality of pixels, a bezel area positioned outside the active area, and at least one opening area positioned inside the active area, at least one opening positioned in the opening area, first signal lines arranged in a first direction and making a detour around the opening in the opening area, and second signal lines arranged in a second direction and making a detour around the opening in the opening area. The opening area includes a first opening area in which the first signal lines are arranged and which is adjacent to the opening, and a second opening area in which the second signal lines intersecting the first signal lines are arranged and which is spaced from the opening.

First claim

What is claimed is:

1. A display device comprising:
a substrate having an active area including a plurality of pixels, a bezel area outside the active area, and at least one opening area inside the active area;
at least one opening in the at least one opening area;
first signal lines arranged in a first direction and making a detour around the at least one opening in the opening area; and
second signal lines arranged in a second direction and making a detour around the at least one opening in the opening area,
wherein the at least one opening area includes:
a first opening area in which the detour of the first signal lines is exclusively arranged and which is located outside the at least one opening; and
a second opening area in which the detour of the second signal lines crossing the first signal lines is exclusively arranged and which is located outside the first opening area and the at least one opening.

2. The display device of claim 1 , wherein the first direction is different from the second direction.

3. The display device of claim 2 , further comprising:
data lines and gate lines configured to define the pixels through a crossing structure of the data lines and the gate lines;
a data driving circuit configured to supply a data voltage to the pixels through the data lines; and
a gate driving circuit configured to supply a gate pulse to the pixels through the gate lines,
wherein the first signal lines are one of the data lines and the gate lines, and the second signal lines are the other lines of the data lines and the gate lines.

4. The display device of claim 1 , wherein the first direction is the same direction as the second direction.

5. The display device of claim 4 , further comprising:
data lines, vertical gate lines, and horizontal gate lines configured to define the pixels through a crossing structure of the data lines, vertical gate lines, and horizontal gate lines;
a data driving circuit configured to supply a data voltage to the pixels through the data lines; and
a gate driving circuit configured to supply a gate pulse to the pixels through the vertical gate lines,
wherein two data lines are disposed at a first column boundary between a first pixel and a second pixel, that are adjacent to each other in a horizontal direction,
wherein one vertical gate line is disposed at a second column boundary between the second pixel and a third pixel, that are adjacent to each other in the horizontal direction,
wherein the horizontal gate lines are respectively connected to the vertical gate lines through contact holes penetrating at least one insulating layer with the at least one insulating layer interposed between them, and
wherein the first signal lines are one of the data lines and the vertical gate lines, and the second signal lines are the other lines.

6. The display device of claim 1 , wherein a separation distance between the first signal lines in the first opening area is less than a separation distance between the first signal lines in the first opening area and the second signal lines in the second opening area that are closest to each other.

7. The display device of claim 1 , wherein a separation distance between the second signal lines in the second opening area is less than a separation distance between the first signal lines in the first opening area and the second signal lines in the second opening area that are closest to each other.
