PROBLEM TO BE SOLVED: To correct brightness values of three kinds of single colors by restraining decrease in a synthetic color reproduction capability of the three kinds of the single colors and restraining increase in an IC chip area. SOLUTION: The maximum values of a 1st color, a 2nd color, and 3rd color of a display panel are expressed by a 1st max, and 2nd max, and a 3rd max, respectively, when they are displayed in each single color, and each gradation level of the 1st color, the 2nd color and the 3rd color is selected, respectively, so that the gradation level-brightness characteristics when normalizing the brightness values of each gradation displayed in the 1st, 2nd, and 3rd single colors by the 1st max, the 2nd max, and the 3rd max coincide with each other, and gradation voltages corresponding to each gradation level in the selected 1st, 2nd, and 3rd colors are applied to each data line.
