    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.
