    摘要： A light guide plate and method for fabricating the same are proposed. An injection molding process is performed to form at least an arc-shaped first opening portion on the light guide plate, so that a concave lens structure is formed on an edge of the first opening portion to be in line with a light source. By such arrangement, the concave lens structure can direct light and achieve a uniform light dispersion effect.

    摘要： A light guide plate is provided. The light guide plate has a transparent substrate having a first optical face and a second optical face, a first micro structure and a second micro structure respectively corresponding to the first optical face and the second optical face. The first micro structure has a tunable composite optical effect with light collection and diffusion functions so as to increase brightness and evenness of exit light. The second micro structure has a design of curved face to destroy total reflection of light, such that bright lines can be effectively prevented from occurrence by avoiding the light outputting from the direction over against the first optical face. A back light unit having the light guide plate is further provided in the present invention.

    摘要翻译： 提供导光板。 导光板具有分别对应于第一光学面和第二光学面的透明基板，具有第一光学面和第二光学面，第一微结构和第二微结构。 第一微结构具有光聚合和扩散功能的可调复合光学效应，以增加出射光的亮度和均匀性。 第二微结构具有弯曲面的设计，以破坏光的全反射，从而通过避免从对第一光学面的方向输出的光，可以有效地防止出现亮线。 在本发明中还提供了具有导光板的背光单元。
