Abstract
A double-sided liquid crystal display device is provided, which includes a light guide plate, a light source, a first liquid crystal panel, a second liquid crystal panel and a reflective Dual Brightness Enhancement Film (DBEF). The light guide plate has a light incident side, a first light exit surface and a second light exit surface. The light source is disposed adjacent to the light incident side. The first liquid crystal panel is disposed opposite to the first light exit surface, and a first lower polarizer of the first liquid crystal panel faces the first light exit surface. The DBEF is disposed between the first lower polarizer and the first light exit surface, and a direction of light transmission axis of DBEF is in parallel with that of the first lower polarizer, and the direction of light transmission axis of DBEF is perpendicular to that of the second upper polarizer.
