The semiconductor layer includes a source region, a drain region, and a channel region disposed between the source region and the drain region. The data conductor includes a data line transmitting a data signal, a source electrode corresponding to the source region, and a drain electrode corresponding to the drain region. A channel step of the semiconductor layer is a height difference between an upper surface in the source region or the drain region and an upper surface in the channel region. The upper surface in the source region or the drain region has a maximum height of the semiconductor layer.

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.
