Abstract
A liquid crystal display device includes plural pixels supplied with video signal voltages via video signal lines, and a video signal line driver circuit for supplying the video signals voltage to the video signal lines. The video signal line driver circuit includes plural differential amplifiers each having a pair of a first input terminal and a second input terminal and amplifying inputted video signals and supplying the amplified video signal to the video signal lines, a plurality of pairs of an inverting input terminal and a noninverting input terminal each pair corresponding to each of the differential amplifiers. The differential amplifiers each have a switching circuit for switching between a first state and a second state with a specified period, the first state being a state where the first input terminal is coupled to the inverting input terminal and the second input terminal is coupled to the noninverting input terminal, and the second state being a state where the first input terminal is coupled to the noninverting input terminal and the second input terminal is coupled to the inverting input terminal.
