Abstract:
1. A display device comprising: a plurality of display elements each displaying an image of any one color from among two or more colors; a plurality of gradation voltage output units each provided for one of said two or more colors and configured to output gradation voltages corresponding to respective display gradation values of a predetermined gradation number, the gradation voltages being different from one another corresponding to color; a plurality of display control voltage supply units each connected to each of two or more display elements among the plurality of display elements and configured to supply a control voltage corresponding to display data of each of the display elements to each of the display elements based on the gradation voltages of the gradation number output by any one of the plurality of gradation voltage output units; and a plurality of gradation voltage selection units each provided to a corresponding one display control voltage supply unit and configured to select the gradation voltages output by any one of the plurality of gradation voltage output units, wherein each of the plurality of gradation voltage selection units is configured to select any one of the plurality of gradation voltage output units in accordance with the color of the display elements which are supplied with the control voltages by the corresponding one display control voltage supply unit, wherein the plurality of display elements includes first and second display elements which are arranged so as to be immediately adjacent to each other, and wherein the plurality of display control voltage supply units includes a first display control voltage supply unit to which the first display element is electrically connected and a second display control voltage supply unit to which the second display element is electrically connected.
