Abstract
A liquid crystal display device includes a video signal processor, a ramp waveform signal generation circuit, and a liquid crystal display element. The video signal processor generates a non-inverted video signal in which video data is not bit-inverted, and an inverted video signal in which the video data is bit-inverted. The ramp waveform signal generation circuit generates a ramp waveform signal having a ramp waveform of a sawtooth wave. In the liquid crystal display element, a plurality of pixels having a liquid crystal are arranged, and a first driving voltage decided based on the non-inverted video signal and the ramp waveform signal and a second driving voltage decided based on the inverted video signal and the ramp waveform signal are alternately applied to the liquid crystal.
