Abstract
A display device includes: a plurality of arranged pixels, each of which includes an electro-optical component, a write-in transistor writing an image signal in a pixel, a maintenance capacity maintaining the image signal written by the write-in transistor, and a driving transistor driving the electro-optical component based on the image signal maintained by the maintenance capacity, wherein the write-in transistor has a plurality of gates, the gate of the driving transistor side among the plurality of gates has a structure in which a channel region is sandwiched between a first gate electrode and a second gate electrode, and the width of the channel region of the gate of the driving transistor side is narrower than the width of the channel region of other gates.
