ABSTRACT:
A counter102counts the accumulated lighting time or the accumulated lighting time and the intensity of lighting of each pixel by a first image signal101A and stores them in a volatile memory103or a nonvolatile memory104. A correction circuit105corrects the first image signal based on the correction data stored previously in a correction data storage section106in accordance with the degree of the degradation of each spontaneous light emitting element by the use of the accumulated lighting time or the accumulated lighting time and the intensity of lighting, and produces a second mage signal101B. By the second image signal101B, a display unit107can provide a uniform screen having no variation in luminance even if the light emitting elements in a part of the pixels are degraded.
