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 has a substrate with a first pixel area and a second pixel area smaller than the first pixel area. First pixels in the first pixel area are connected with first scan lines. Second pixels in the second pixel area are connected with second scan lines. A first scan driver supplies a first scan signal to the first scan lines, and a second scan driver supplies a second scan signal to the second scan lines. A first signal line supplies a first driving signal to the first and second scan drivers. The first signal line includes first sub signal line to supply the first driving signal to the first scan driver, a second sub signal line to supply the first driving signal to the second scan driver, and a first load matching resistor connected between the first sub signal line and the second sub signal line.
