Liquid crystal display device switchable between reflective mode and transmissive mode by employing active reflective polarizer |
摘要 |
A liquid crystal display (LCD) device that is switchable between a transmissive mode and a reflective mode is provided. The LCD device includes a backlight; an active reflective polarizer which operates as a reflector that reflects incident light or as a reflective polarizer that reflects light of a first polarization and transmits light of a second polarization perpendicular to the first polarization, based on whether a magnetic field is applied; and a liquid crystal panel that modulates incident light to form images. The liquid crystal panel includes a liquid crystal layer, a first polarizer that is disposed on a rear surface of the liquid crystal layer and faces the active reflective polarizer, and a second polarizer that is disposed on a front surface of the liquid crystal layer.
