Abstract
A liquid crystal display (200) includes a transparent substrate (25), a light guide plate (28) disposed under the substrate, and a light source (29) disposed above the light guide plate at a thin side of the substrate. The light guide plate includes a top surface (280). An area of the top surface corresponding to the light source defines a light incident area, and another area of the top surface corresponding to the substrate defines a light emitting area.
Claims13
A liquid crystal display, comprising:
- a transparent substrate;
- a light guide plate disposed under the substrate;
- and
- a light source disposed above the light guide plate at a thin side of the substrate;
- wherein the light guide plate comprises a top surface and a side surface adjacent to the top surface, an area of the top surface corresponding to the light source defines a light incident area, another area of the top surface corresponding to the substrate defines a light emitting area, and the side surface comprises a continuous V-cut structure.

A liquid crystal display, comprising:
- a light guide plate comprising a generally rectangular portion and a wedge-shaped portion at an end of the rectangular portion, the wedge-shaped portion comprising an inclined surface with a continuous V-cut structure;
- a transparent substrate disposed above the light guide plate;
- and
- a light source disposed above the light guide plate;
- wherein the rectangular portion of the light guide plate corresponds to the substrate, the wedge-shaped portion of the light guide plate corresponds to the light source, light beams emitting from the light source enter the wedge-shaped portion of the light guide plate, the inclined surface of the wedge-shaped portion reflects the light beams in the wedge-shaped portion generally toward the rectangular portion of the light guide plate, and at least a portion of the light beams exit the rectangular portion of the light guide plate and enter the substrate.
