A voltage selection unit selects, based on a grayscale value represented by e.g. 10-bit grayscale data D<9:0>, two voltages Vb1 and Vb2 from among γ-correction voltages Va0, Va1, Va16, . . . , Va1008, Va1022, and Va1023 generated from one reference voltage. A divided voltage generation unit generates divided voltages Vc1-Vc16 by dividing a voltage difference between the Vb1 and Vb2 into 16 equal parts. The divided voltage generation unit makes a voltage value of the Vc1 that of the Va0 when the Va0 is selected, makes a voltage value of the Vc2 that of the Va1 when the Va1 is selected, makes a voltage value of the Vc15 that of the Va1022 when the Va1022 is selected, and makes a voltage value of the Vc16 that of the Va1023 when the Va1023 is selected. A DAC selects one divided voltage from among the Vc1-Vc16 based on lower-order four bits D<3:0>.
