    摘要: A light guide plate includes a light incident surface for receiving light, first and second light emission surfaces for emitting light at a first light emission angle with respect to the first and second light emission surfaces, and a light reflection pattern formed on the first light emission surface, for reflecting the light toward the second light emission surface. The reflected light from the light reflection pattern exits the second light emission surface at a second light emission angle with respect to the second light emission surface, and the second light emission angle is larger than the first light emission angle. The light reflection pattern includes multiple dots each having a prim pattern on their surface and light reflecting surfaces elongated in a selected direction. The adjacent light reflecting surfaces meet each other at their elongated edges to form a prism shape.
