  • Publication number: 20160216551
    Abstract: A normally white type liquid crystal display device comprises a liquid crystal display, a backlight source and a dimmer film. The dimmer film is located on one surface, far away from the backlight, of the liquid crystal display, or in the liquid crystal display, or between the liquid crystal display and the backlight source, or in the backlight source. Under the circumstances that a voltage is not applied between an upper polarizer and a lower polarizer of the normally white type liquid crystal display device and a voltage is not applied to the backlight source, the transmittance of incident light and reflected light is reduced due to the existence of the dimmer film.
