摘要： A phase difference plate and a liquid-crystal layer are provided between a polarizing plate and a selective reflection layer formed of cholesteric liquid crystal. A first color filter layer is provided on the polarizing plate side of the selective reflection layer. On the back side of the selective reflection layer, a second color filter layer is arranged. On the back side of the second color filter layer, a backlight is provided. When a liquid-crystal display device functions as a reflective liquid-crystal display device, light entering through the polarizing plate is reflected totally by the selective reflection layer and passes through the first color filter layer twice. When the liquid-crystal display device functions as a transmission liquid-crystal display device, light from the backlight passes through the selective reflection layer. Then, the light passes through the second and first color filter layers once and is outputted.

摘要： A flat panel display device includes a polarizer, a polarized light reflection layer made of a cholesteric liquid crystal layer, a fixed retarder layer to delay an incident light phase by &lgr;/4, and a variable retarder layer to shift an incident light phase by &lgr;/2 in response to applied voltages. The fixed and variable retarder layers are held between the polarizer and the polarized light reflection layer. A retardation plate and a second polarizer are disposed behind the polarized light reflection layer to transform incident light into a circularly polarized light component of which rotation direction is the same as that of the circularly polarized light selectively reflected from the polarized light reflection layer. The flat panel display device is used as reflection type and semi-transmission type displays with high light efficiency of light utilization and high brightness as well as low power consumption.
