Abstract

A liquid crystal display device () includes: a liquid crystal layer () held between a pair of substrates (), the liquid crystal layer containing one or more types of positive liquid crystal compounds whose dielectric anisotropy is positive and one or more types of negative liquid crystal compounds whose dielectric anisotropy is negative, a total content of the positive liquid crystal compounds not being smaller than a total content of the negative liquid crystal compounds; a pixel electrode () provided in the pair of substrates, the pixel electrode having a plurality of linear portions and a slit; and a common electrode () insulated from the pixel electrode, wherein the pixel electrode and the common electrode apply across the liquid crystal layer a pixel voltage of positive polarity and a pixel voltage of negative polarity alternately at a frequency lower than 60 Hz.
