Abstract

Provided is a liquid crystal display device that can achieve high-speed response in both rise time and fall time and has a high transmittance, a high contrast ratio, and excellent viewing angle characteristics. The liquid crystal display device provides color display using a field sequential driving system where each frame period includes subframe periods and includes: a liquid crystal display panel; a light source that irradiates the liquid crystal display panel with lights of multiple colors; and a controller that drives the light source to time-divisionally irradiate the liquid crystal display panel with the lights of multiple colors. The liquid crystal display panel includes, sequentially in the following order: a first substrate including pixel electrodes; a first alignment film; a liquid crystal layer; a second alignment film; and a second substrate including a common electrode.
