Abstract: A display device includes, on an insulating substrate, a plurality of scanning lines, a plurality of signal lines, a plurality of sub-pixel regions each surrounded by a pair of scanning lines and a pair of signal lines, a plurality of semiconductor layers in the sub-pixel regions, and a base electrode connected to one end of the semiconductor layer. The other end of the same is connected to one of the pair of signal lines. When it is assumed that a signal connected to the semiconductor layer is a first signal line while a signal line not connected to the semiconductor layer is a second signal line in each sub-pixel region, a distance between the first signal line and the semiconductor layer is larger than a distance between the second signal line and the semiconductor layer at a connecting position between the semiconductor layer and the base electrode in plan view.
