Amplifier circuits (AMPi, AMPj) are provided corresponding to data lines (DLi, DLj) arranged corresponding to columns of display pixels (PX). In the amplifier circuit, a non-inversion input of a differential amplifier circuit ( 32 ) is connected to the corresponding data line, and an inversion input node (N 2 ) is connected to a capacitance element ( 34 ). Before pixel data of a displaying pixel element is read onto the data line, the non-inversion input of the differential amplifier circuit is precharged to a predetermined voltage level, and an output node of the differential amplifier circuit is coupled to the inversion input node (N 2 ). The differential amplifier circuit operates as a voltage follower, and the capacitance element stores a comparison reference voltage including information corresponding to an offset of the differential amplifier circuit. Thereafter, data of the displaying pixel element is read onto the data line, and is amplified by the amplifier circuit so that the pixel data can be accurately amplified while canceling the offset of the differential amplifier circuit.
