Abstract

Disclosed is a display device including a display panel that includes a first area and a second area. The second area is divided into a first side area and a second side area around a central axis. The display panel includes a first side normal pixel disposed in each of first and second rows of the first side area, a first side non-normal pixel disposed in the second row among the first and second rows of the first side area, a second side normal pixel disposed in each of first and second rows of the second side area, and a second side non-normal pixel disposed in the first row among the first and second rows of the second side area. Each of the first side non-normal pixel and the second side non-normal pixel further includes a connection wiring connecting a data line and a pixel circuit to each other.
