A light guide plate includes a plastic plate (1) with a high light transmission rate, and a receiving hole (11) to receive a light source (2) is formed in the plastic plate (1). By using the structure of the receiving hole (11) to replace the design of the rectangular grooves with protrusions in the prior art, the light guide plate can adequately apply sides of the light source for dispersion, and further increase the guide proportion, in order to greatly improve the entire brightness and the symmetry. |
