PROBLEM TO BE SOLVED: To decrease variation in an output voltage of a DAC responding to a plurality of gradation voltage generation circuits and to improve picture qualities.SOLUTION: A display device includes: a first gradation voltage generation circuit that receives constant voltages supplied from first and second constant voltage circuits through first and second wiring lines and generates and supplies a plurality of gradation voltages to a first group of gradation lines; a second gradation voltage generation circuit that receives constant voltages supplied from third and fourth constant voltage circuits through third and fourth wiring lines and generates and supplies a plurality of gradation voltages to a second group of gradation lines; a first group of switching circuits that connect gradation lines selected from the first group of gradation lines to input terminals of a first group of amplifiers; and a second group of switching circuits that connect gradation lines selected from the second group of gradation lines to input terminals of a second group of amplifiers. A difference in a resistance value between the first and third wiring lines and a difference in a resistance value between the second and fourth wiring lines are smaller than 1/8 of a resistance value of one division resistance.SELECTED DRAWING: Figure 3
