Claim:
1. A display device comprising: a light-emitting portion configured to constitute a pixel and emit light in response to a drive current; a writing transistor configured to write a video signal into a pixel capacitance; a driving transistor configured to control the drive current of the light-emitting portion on the basis of the video signal written in the pixel capacitance; a first metal layer configured to constitute a drain and a source of each of the driving transistor and the writing transistor; and a second metal layer configured to constitute a gate of each of the driving transistor and the writing transistor, wherein the drain and the source of each of the driving transistor and the writing transistor in the first metal layer are opposed to each other in both a linear predetermined direction, and in reverse directions to each other relative to the linear predetermined direction, and wherein the drain of the driving transistor, the source of the driving transistor, the source of the writing transistor, and the drain of the writing transistor are arranged in this order in the linear predetermined direction.
