Abstract
A display includes a display device having a first polarizer and a second polarizer or a reflector, and a display layer disposed between the first polarizer and the second polarizer or the reflector. A liquid crystal layer is disposed between the display layer and one of the first polarizer and the second polarizer or reflector. The 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. 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.
