Liquid Crystal Display Device and Electronic Device

摘要

A flicker of an FFS liquid crystal display device that is driven at a low refresh rate is reduced. In an FFS liquid crystal display, a pixel electrode and a first common electrode included in a liquid crystal element are formed on an element substrate side, and a second common electrode is formed on another substrate (counter substrate) side. By making the first and second common electrodes have the same potential, generation of a residual DC voltage can be suppressed in a pixel. Thus, even when a refresh rate is lowered, change in transmittance of a pixel can be suppressed in a data retention period, so that a flicker can be reduced.

1. A liquid crystal display device comprising:
a first substrate and a second substrate facing each other; a liquid crystal layer between the first substrate and the second substrate; a pixel electrode and a first common electrode between the first substrate and the liquid crystal layer; and a second common electrode between the second substrate and the liquid crystal layer, wherein the pixel electrode faces the first common electrode with an insulating layer between the pixel electrode and the first common electrode, wherein the second common electrode faces the first common electrode with the liquid crystal layer between the second common electrode and the first common electrode, wherein a data signal corresponding to image data is supplied to the pixel electrode, and wherein a same potential is supplied to the first common electrode and the second common electrode.
