Abstract

A display device includes first pixels configured to be positioned in a first pixel area and configured to be connected to first scan lines; first scan stage circuits configured to be positioned in a first peripheral area that is positioned outside the first pixel area and configured to supply first scan signals to the first scan lines; second pixels configured to be positioned in a second pixel area and configured to be connected to second scan lines; and second scan stage circuits configured to be positioned in a second peripheral area that is positioned outside the second pixel area and configured to supply second scan signals to the second scan lines. A gap between adjacent second scan stage circuits is larger than a gap between adjacent first scan stage circuits.

Claims (62)

1. A display device comprising:

second scan stage circuits positioned in a second peripheral area and configured to supply second scan signals to second scan lines, wherein the second scan stage circuits are arranged beyond the first direction; and

dummy scan stage circuits positioned between adjacent second scan stage circuits.

2. The display device according to claim 1 ,

wherein at least some of the second scan stage circuits have slopes with reference to a second direction, and

wherein the first scan stage circuits do not have slopes with reference to the second direction.

3. The display device according to claim 1 , wherein a number of the dummy scan stage circuits is set differently according to a position.

4. The display device according to claim 3 ,

wherein the second scan stage circuits include a first pair of the adjacent second scan stage circuits and a second pair of the adjacent second scan stage circuits,
