Abstract:
A liquid crystal display device, comprising:a first transparent substrate; a second transparent substrate; a liquid crystal layer between the first transparent substrate and the second transparent substrate, the liquid crystal being horizontally arranged when a voltage is not applied; a linear polarizer on the second transparent substrate; a cholesteric liquid crystal circular polarizer provided on the first transparent substrate; backlight disposed under the cholesteric liquid crystal circular polarizer, the backlight generating unpolarized light; and a cholesteric liquid crystal color filter provided on the first transparent substrate in order to be situated between the cholesteric liquid crystal circular polarizer and the liquid crystal layer; and an absorptive color filter on one of the first or second transparent substrates in order to prevent any color shift according to viewing angle which can be generated from the cholesteric liquid crystal circular polarizer, wherein the liquid crystal display device is a transmission-reflection liquid crystal display device.
