Abstract
In a display device 100, a reflective polarizer 110, a polarizer 120, a retarder 130, a liquid crystal panel 140, a polarizer 150, and a backlight 160 are disposed sequentially from the viewing side. When the liquid crystal panel 140 is set in a light blocking state or the backlight 160 is set in an unlit state, the reflection of an outside light 'O' turns the display screen into a mirror state. When the backlight 160 is set in a lit state to drive the liquid crystal panel 140, a transmitted light 'T' allows a particular display screen to be visually recognized.
