摘要： When a backlight 15 is turned on in a dark environment, white light emerging from the surface of a light guide plate 15b passes through a polarizer 12 and a retardation film 14, enters the interior of the liquid crystal cell, passes through openings of reflective electrodes 7, and is introduced into a liquid crystal layer 3. The light introduced into the liquid crystal layer 3 passes through a color filter 5, emerges from the liquid crystal cell, and passes through the retardation film 13 and the polarizer 11 towards the exterior. In a lighted environment, the light incident on the polarizer 11 passes through the liquid crystal layer 3, is reflected by the reflective electrode 7, and passes through the polarizer 11 again and is emitted towards the exterior.
