Abstract
To alleviate an afterimage phenomenon caused by a hysteresis characteristic of a drive transistor. Current driven type light emitting elementsare provided for each of pixelsthat are arranged in a matrix shape, and current of the light emitting elementsis controlled using drive TFTsthat operate by receiving data voltage on a gate. At least two power supply voltages (PVDDa, PVDDb) for supply to each pixel are provided, one being set to a voltage such that current corresponding to a data voltage flows in the drive TFT, the other being set to a voltage beyond a variation range of data voltage and that reverse biases the drive TFT, and the two power supply voltages are switched and supplied to each pixel
