Light guide plate for liquid crystal display |
摘要 |
A light guide plate (3) includes a parallelepiped block. The block includes an input surface (31) for receiving light beams irradiated from a light source; two side surfaces perpendicularly adjoining the incident surface; an output surface (32) perpendicularly adjoining the incident surface and the side surfaces; and a bottom surface (33) opposing to the output surface. An array of prisms (34) is integrally formed on the output surface. Each prism is shaped as a square pyramid. All the prisms have a same size and are arranged contiguously with each other. Alternatively, the light guide plate may be a wedge-shaped block (3'). A rectangular array of prisms (34') is integrally formed on an output surface (32') thereof. Each prism is shaped as a square pyramid. The prisms are arranged contiguously with each other, and sizes of the prisms gradually decrease from a thick end to a thin end of the block.
