Abstract:
1. A semiconductor device comprising: a substrate having an insulating surface; a gate electrode layer over the substrate; a gate insulating layer over the gate electrode layer; an oxide semiconductor layer over the gate insulating layer; a source electrode layer and a drain electrode layer electrically connected to the oxide semiconductor layer; an insulating layer over and in contact with the oxide semiconductor layer, the source electrode layer, and the drain electrode layer; a light-transmitting conductive layer over the insulating layer, the light-transmitting conductive layer being electrically connected to one of the source electrode layer and the drain electrode layer; and a cathode of a light-emitting element over and in contact with the light-transmitting conductive layer, wherein the oxide semiconductor layer comprises a region with a smaller thickness than a region overlapping with the source electrode layer or the drain electrode layer, and wherein an end portion of the oxide semiconductor layer has a curved surface.
