Abstract:
1. A liquid crystal display device that is capable of switching viewing angle characteristics, the liquid crystal display device comprising: a viewing-angle-control liquid crystal panel provided on a viewing surface side between a viewing surface and a backlight, the viewing-angle-control liquid crystal panel including a fourth polarizing member, a viewing-angle-control liquid crystal cell, and a third polarizing member provided in this order so as to be at least partially overlapped from the viewing surface; a display liquid crystal panel provided on a backlight side between the viewing surface and the backlight, the display liquid crystal panel including a second polarizing member, a display liquid crystal cell, and a first polarizing member provided in this order so as to be at least partially overlapped from the viewing surface; and a retardation member for setting a viewing restricted direction, the retardation member provided between at least the third polarizing member and the second polarizing member, the fourth polarizing member having a transmission axis in a direction that is different from a direction of a transmission axis of the second polarizing member.
