摘要 <p>To alleviate an afterimage phenomenon caused by a hysteresis characteristic of a drive transistor. Current driven type light emitting elements 3 are provided for each of pixels 6 that are arranged in a matrix shape, and current of the light emitting elements 3 is controlled using drive TFTs 2 that 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 2, the other being set to a voltage beyond a variation range of data voltage and that reverse biases the drive TFT 2, and the two power supply voltages are switched and supplied to each pixel 6.</p>
