ABSTRACT:
The present invention provides an active-matrix electro-optical device allowing clear multi-gray-scale color display. In the electro-optical display according to the present invention, a plurality of pixels included in a pixel portion have a first and a second source signal lines, a first and a second gate signal lines, and a power source supply line. Each of the pixels has a first TFT for switching, a second TFT for switching, a TFT for driving and a light emitting element.
