Patent ID: 8305309

Claim:
A display device comprising: a pixel array unit having pixels disposed in a matrix shape, each pixel including an electro-optical element, a write transistor for sampling and writing an input signal voltage provided from a signal line placed at a signal voltage or a reference potential, a holding capacitor for holding the signal voltage written by the write transistor, and a driver transistor for driving the electro-optical element in response to the signal voltage held in the holding capacitor; a scan circuit for selectively scanning each pixel in the pixel array unit at a row unit basis; and a plurality of power source supply scan circuits for selectively supplying a first potential and a second potential lower than the first potential to a power supply line to supply current to the driver transistors, synchronously with line sequential scanning by the scan circuit, wherein, at a beginning of line sequential scanning, the second potential is lower than the reference potential at the signal line; and wherein the plurality of power source supply scan circuits are disposed on both sides of the pixel array unit by sandwiching the pixel array unit, and one of the plurality of power source supply scan circuits is disposed between the pixel array unit and the scan circuit.
