Abstract: A display device includes a display panel that includes a display area and a first peripheral area adjacent to the display area. The first peripheral area includes a bendable region extending across the display panel and a plurality of signal lines partially included in the bendable region. The plurality of signal lines includes a first and second group adjacent to each other in the bendable region. The first group includes two or more first signal lines that transmit signals of a first polarity. The second group includes two or more second signal lines that transmit signals of a second polarity different from the first polarity. The first and second group are separated by a first interval, and signal lines within the first or second group are separated by a second interval. The first interval is greater than the second interval.

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.
