ABSTRACT:
An active matrix display device capable of vivid color display having many tones is provided. The display device is characterized in that each of a plurality of pixels comprises a first TFT for switching, a second TFT for switching, a TFT for erasing, a TFT for EL driving, and an EL element, driving of the TFT for EL driving is controlled by the first TFT for switching, the second TFT for switching, and the TFT for erasing, and light emission by the EL element is controlled by the TFT for EL driving.
