Abstract
Provided is a liquid crystal display device including: a liquid crystal panel including display units for displaying an image using a veil-view function; and a control circuit. The display units each include a pair of sub-pixels including a first sub-pixel and a second sub-pixel. The liquid crystal panel sequentially includes an active matrix substrate, a first alignment film, a liquid crystal layer containing liquid crystal molecules, a second alignment film, and a counter substrate. The active matrix substrate includes first and second electrodes that are stacked via a first insulating layer or that face each other on the first substrate. At least one of the first or second electrode is disposed for each first sub-pixel and for each second sub-pixel. The counter substrate includes a third electrode. The control circuit is configured to switch between application of alternating voltage and application of constant voltage to the third electrode.
