Abstract
A display device controls a signal applied to the n dots such that a sum of luminance of n dots (n is an integer of 1 or more) is virtually equal to an original luminance of the defective dot on the assumption that the n dots, which are adjacent to an electrically uncontrollable dot, are not originally illuminated. The display device also controls a signal applied to dots adjacent to the defective dot so as to display a color which is closer to an original color obtained by input signals to the defective dot and the adjacent dots.
