Abstract
A surface texture of a light guide plate (101), use and manufacturing method thereof, wherein the surface texture includes convex-concave structures (301, 401, 501), the curved surfaces of the convex-concave structures are optically smooth, the arithmetical mean deviation of the surface roughness profiles isn't greater than ⅛ shortest wavelength of working light in the light guide plate. By using the light guide plate with the surface texture, not only can total reflection be performed in the light guide plate, but also the outer surface of the light guide plate appears to have the effect similar to diffuse reflection, so that specular reflection of the surface of the classical light guide plate can be overcome.
