<P>PROBLEM TO BE SOLVED: To provide a display device, which reduces difference of degradation in a display element for every pixel, and also which reduces the variations of light emission in the display element of the pixel. <P>SOLUTION: The display device is configured such that the accumulated lighting time of only a specified pixel is not lengthened. Accordingly, gray scales of display patterns are varied, so that the difference of degradation in the display element for every pixel is not increased, or a specified display pattern is not fixed and displayed at a specific region, or a pixel whose degradation is delayed is deteriorated so that the accumulated lighting time for every pixel becomes equal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
