PROBLEM TO BE SOLVED: To reduce cost that accompanies the change in the resistance value of a gradation correction resistance element in a gradation voltage generation circuit. SOLUTION: A driving driver (30) comprises a gradation voltage generating circuit (37) and a control part (39). The gradation voltage generating circuit (37) comprises a plurality of series-connected gradation correction resistance elements (R0-R62) and divides standard voltages (V0-V7) by the plurality of the gradation correction resistance elements (R0-R62), to generate a plurality of gradation voltages. The control part (39) selects the output gradation voltage, corresponding to the display data (DATA) of the plurality of the gradation voltages, and outputs it to a display part (10). Among the plurality of the gradation correction resistance elements (R0-R62)(55), the selection gradation correction resistance element (55') and the other gradation correction resistance elements (55) are different in the width (W).
