An exemplary prism sheet includes a base including an upper surface and a plurality of lenses disposed on the upper surface. The upper surface is a wavy surface. A liquid crystal display device using the prism sheet is also provided.

An exemplary double-sided liquid crystal display (LCD) () includes a first liquid crystal panel (), a first optical film assembly (), a light guide plate (), a second optical film assembly (), and a second liquid crystal panel () 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.

An exemplary backlight module () includes a light guide plate () and at least one point illuminator (). The light guide plate includes a first side surface (), and a protrusion () outwardly extending from the first side surface. The protrusion includes at least one second side surface () oblique to the first side surface. The at least one point illuminator is adjacent to the least one second side surface.

A prism sheet () includes a substrate () and a plurality of prism structures (). The substrate includes a plurality of diffusing particles () dispersed therein. The prism structures are at a light output side of the substrate. The diffusing particles can diffuse light beams traveling through the substrate. This configuration performs the same function as that of a diffusing sheet of a conventional backlight module. The prism structures can gather light beams to improve a brightness of a backlight module () incorporating the prism sheet. Thus, the backlight module can provide bright and uniform light at a low cost and while having a reduced thickness.

A light guide plate () includes a light incident surface (), a light emitting surface () adjoining the light incident surface, a bottom surface () opposite to the light emitting surface, and a plurality of holes (). Each hole has at least one open end terminating at the light emitting surface or the bottom surface. The holes may be through holes or blind holes. When incident light beams reach the holes, the light beams are reflected or refracted in directions toward the light emitting surface. Therefore a distance traveled by a portion of the light beams in the light guide plate is shortened, and the loss of light energy is reduced. This enables the light guide plate to provide a high ratio of light utilization. Additionally, the through holes reduce the weight of the light guide plate. The light guide plate can be generally rectangular or wedge-shaped.
