Abstract
In a liquid crystal display device including a display liquid crystal panel and a viewing-angle-control liquid crystal panel and capable of switching viewing angle characteristics, a half wavelength plate for setting a viewing restricted direction is provided between the display liquid crystal panel and the viewing-angle-control liquid crystal panel. This makes it possible to realize a liquid crystal display device that allows a viewing restricted direction to be set as appropriate.
