Abstract
In a display device in which pixels are arranged in a matrix, each pixel has an electro-optical element, a write transistor that writes a video signal, a drive transistor that drives the electro-optical element in accordance with the video signal written by the write transistor, a storage capacitor that is connected between a gate electrode and a source electrode of the drive transistor to store the video signal written by the write transistor. Current is prevented from flowing to the drive transistor when the write transistor writes the video signal.
