Abstract:
1. A display comprising: a display device having a first polarizer, one of a second polarizer and a reflector, and a display layer disposed between the first polarizer and said one of the second polarizer and the reflector; and a liquid crystal layer disposed between the display layer and one of the first polarizer and said one of the second polarizer and the reflector; wherein liquid crystal molecules of at least one region of the liquid crystal layer are switchable between a first state in which the display has a first display mode with a first viewing angle range and a second state in which the display has a second display mode having a second viewing angle range smaller than the first viewing angle range, the liquid crystal layer having the same sign of retardation in the first state as in the second state; and in the second state, liquid crystal molecules of the at least one region are tilted with respect to the normal axis of the display over at least a portion of the thickness of the liquid crystal layer, and lie substantially parallel to a plane defined by the normal axis of the display and the transmission axis or absorption axis of the first polarizer or one of the first and second polarizers.
