  • Patent number: 11915652
    Abstract: A display includes a plurality of pixels in a non-quadrangular display area and a plurality of first driving circuits and a plurality of second driving circuits in a peripheral area of the display area. Each of the pixels is connected to a first signal line in a first direction and a second signal line in a second direction crossing the first direction. Each of the first driving circuits outputs a first signal to the first signal line of a corresponding one of the pixels. Each of the second driving circuits outputs a second signal to the second signal line of a corresponding one of the pixels. The number of second driving circuits between neighboring first driving circuits is different depending on a position in the peripheral area.
