Display device
According to one embodiment, a display device comprises a display panel, first and second driver chips. The display panel includes first and second edge portions, a display area between the first and second edge portions in a first direction, first signal lines extending to the display area, and second signal lines extending to the display area. The first driver chip is connected to the first edge portion to supply video signals to the first signal lines. The second driver chip is connected to the second edge portion to supply video signals to the second signal lines. Number N of the first signal lines and number M of the second signal lines are alternately arranged in a second direction.
1 . A display device comprising:
a display panel including a first edge portion, a second edge portion, a display area located between the first edge portion and the second edge portion in a first direction, a plurality of first signal lines extending to the display area, and a plurality of second signal lines extending to the display area;
a plurality of first driver chips including the first driver chip, which are arranged in the second direction, and each of which supplies video signals to the plurality of first signal lines;
a plurality of second driver chips including the second driver chip, which are arranged in the second direction, and each of which supplies video signals to the plurality of first signal lines;
a plurality of first flexible substrates connected to the first edge portion; and
a plurality of second flexible substrates connected to the second edge portion,
wherein
number N of the first signal lines and number M of the second signal lines are alternately arranged in a second direction intersecting the first direction,
the plurality of first driver chips are mounted on the plurality of first flexible substrates, respectively,
the plurality of second driver chips are mounted on the plurality of second flexible substrates, respectively,
the first driver chip supplies video signals having polarities alternately different one by one to the plurality of first signal lines arranged in the second direction, and
the second driver chip supplies video signals having polarities alternately different one by one to the plurality of second signal lines arranged in the second direction.
2 . The display device of claim 1 , wherein

7 . The display device of claim 1 , wherein
the display area includes a plurality of pixels, and
each of the plurality of pixels includes number, different from the N and the M, of sub-pixels.
8 . The display device of claim 7 , wherein
at least one of the sub-pixels constituting one pixel is connected to one of the plurality of first signal lines, and rest of the sub-pixels is connected to one of the plurality of second signal lines.
9 . The display device of claim 1 , wherein
at least one of the plurality of first signal lines includes a first inclined portion extending in a direction intersecting the first direction at the first edge portion, and
at least one of the plurality of second signal lines includes a second inclined portion extending in a direction intersecting the first direction at the second edge portion.
10 . The display device of claim 1 , further comprising:
a first substrate; and
a second substrate overlapping the first substrate,
wherein
a width of the second substrate in the first direction is smaller than a width of the first substrate in the first direction, and
the first edge portion and the second edge portion correspond to areas of a surface of the first substrate, the areas do not overlap the second substrate.
