Abstract:
Disclosed herein is a display device capable of displaying an image with two or more gray levels. The display device includes: a voltage division circuit adapted to generate a plurality of voltages using a resistance division circuit; a gamma correction section adapted to gamma-correct the image using the voltages generated at division points of the resistance division circuit; an amplification circuit adapted to amplify a given voltage and supply the amplified voltage to at least one of the division points of the resistance division circuit; and an adjustment section adapted to adjust an amplification factor of the amplification circuit.
