Abstract: A display device includes first pixels in a first pixel area, second pixels in a second pixel area, first stages, second stages, and third stages. The first pixels are electrically connected to first signal lines, second signal lines, and data lines. The second pixels are electrically connected to at least a portion of third signal lines, fourth signal lines, or data lines. The first stages supply a first signal to the first and third signal lines. The second stages supply a second signal to the second signal lines and at least one of the fourth signal lines. The third stages supply the second signal to the fourth signal lines other than the at least one fourth signal line connected to the second stages. The second stages are spaced from the third stages.

Abstract: A display device includes a substrate including a first pixel region and a second pixel region having a smaller area than the first pixel region. The second pixel region is connected to the first pixel region. A first pixel is provided in the first pixel region and a second pixel is provided in the second pixel region. A first line is connected to the first pixel and a second line is connected to the second pixel. A dummy unit overlaps at least one of the first line and the second line, and compensates for a difference in load values between the first and second lines.
