ABSTRACT:
A display device includes a plurality of display elements and a correction circuit which outputs signals obtained by performing correction on input signals to the respective display elements, and the correction circuit performs the correction so that a spatial frequency distribution of luminance obtained by driving the respective display elements by using the signals obtained by performing the correction on the input signals indicative of predetermined luminance becomes a spatial frequency distribution in which a predetermined frequency component is reduced from among frequency components contained in a spatial frequency distribution of luminance obtained by driving the respective display elements without performing the correction on the input signals indicative of the predetermined luminance and at least a portion of frequency components lower than the predetermined frequency component is left.
