Abstract:
Provided is a liquid crystal display device including: a liquid crystal panel; and a control circuit. The liquid crystal panel sequentially includes an active matrix substrate, a first alignment film, a liquid crystal layer containing liquid crystal molecules having a negative anisotropy of dielectric constant, a second alignment film aligning the liquid crystal molecules at an angle of 10° or greater and 30° or smaller, and a counter substrate. The active matrix substrate includes a first substrate, and a first electrode and a second electrode that are stacked via a first insulating layer or that face each other on the first substrate. The counter substrate sequentially includes a second substrate, a third electrode, a second insulating layer, and a fourth electrode. The control circuit is configured to switch between application of alternating voltage and application of constant voltage to the third and/or fourth electrode according to a display mode.
