PROBLEM TO BE SOLVED: To enable readjustment of color tones of a display device even if conversion data of luminance and conversion data of chromaticity are not fully rewritten when a display unit constituting the display device is exchanged and to facilitate the adjustment of the luminance and chromaticity for all the light emitting elements constituting a display module in constituting the display module by combining a plurality of the display units. SOLUTION: The display device includes a first color conversion means (22) for converting the luminance and chromaticity over the entire part of the display module and a gradation conversion means (24) for converting the gradation characteristics of the image data after the color conversion and the interior of the display unit includes a reverse gradation conversion means (32) for returning the gradation characteristics to the original characteristics and a second color conversion means (32) for converting the luminance and chromaticity.
