摘要： A display device includes a substrate having a first region in which an image is displayed, a second region in which an image is not displayed, and a bending region connecting the first region and the second region. The bending region is configured to bend along a bending axis which extends in a first direction. A plurality of pad terminals is disposed within the second region. A first width of the bending region, measured along the first direction, is narrower than a second width of the second region, measured along the first direction.

摘要： 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.
