Abstract
There is provided a display device including a light-emitting portion configured to constitute a pixel and emit light by a drive current, a writing transistor configured to write a video signal into 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.
