Abstract

According to one embodiment, a display device includes a first subpixel and a second subpixel. An area, in a plan view, surrounded by a first signal line, a second signal line, a first scanning line, and a second scanning line and including a first pixel electrode is a first area. An area, in a plan view, surrounded by the first signal line, the second signal line, the second scanning line, and a third scanning line and including a second pixel electrode is a second area. The first area has a first distance in the first direction and the second area has a second distance in the first direction. The first distance is greater than the second distance.
