Abstract
To determine a deterioration and maintain a high-quality image without unevenness of brightness by performing a precise correction, a detection scanning line for selecting a pixel which detects a deterioration of a pixel, a detection line for informing the outside of the display area of the property of a pixel selected for detecting the deterioration, a deterioration determination means for determining a deterioration amount based on a voltage corresponding to a current detected by the detection line, and a deterioration correction means (computation circuit) for reflecting the determination result of the deterioration determination means in image data supplied to the pixel, are provided.
