    摘要: An exemplary double-sided liquid crystal display (LCD) (200) includes a first liquid crystal panel (212), a first optical film assembly (211), a light guide plate (230), a second optical film assembly (211), and a second liquid crystal panel (222) arranged in that order from bottom to top. An area of the second liquid crystal panel is less than an area of the first liquid crystal panel, and an area of the second optical film assembly is less than an area of the first optical film assembly. The second optical film assembly of the double-sided LCD has a size no larger than that needed to perform its function in respect of light beams propagating therethrough from the light guide plate to the second liquid crystal panel. Therefore, the double-sided LCD is cost-efficient.
