Abstract

A liquid crystal display device having a liquid crystal display element having a plurality of pixels. The video signal line driver circuit includes a plurality of amplifiers each of which has a pair of a first input terminal and a second input terminal, and a plurality of pairs of an inverting input terminal and a noninverting input terminal. Each of the plurality of amplifiers has a switching circuit which switches between a first state and a second state, based on a switching control signal supplied with a switching repetition period equal to double a display line repetition period.
