In one embodiment of the present application, a liquid crystal display device is disclosed, in which increased power consumption due to an excessive DAC capability and reduced display quality due to a deficient DAC capability do not occur as a result of dynamically adjusting the DAC capability such that variation in the characteristics of the liquid crystal panel is compensated. The liquid crystal display device comprises a digital-to-analog converter circuit that converts data signals inputted as digital signals to analog signals; a source driver that distributes and inputs analog signals output from the digital-to-analog converter circuit to a plurality of source lines Y; a differential amplifier that compares the voltage V1 detected on the input side of a source line Y and voltage V2 detected on the side opposite the input side of the source line Y; and a correcting circuit that corrects the output of the digital-to-analog converter circuit that corrects the output of the digital-to-analog converter circuit based on the comparison results of the differential amplifier.
