Abstract
The utility model discloses a light guide plate possessing a light diffusion function. The light guide plate is provided with a transparent substrate and a diffusion film. The diffusion film is adhered to a right side of the transparent substrate. Because several light guide spots are arranged on a back side of the transparent substrate, the transparent substrate possesses a light guide function and a line light source can be converted into an area source. Because the external surface of the diffusion film is an uneven rough surface, a light diffusion function is possessed. Therefore, the light guide plate of the utility model possesses dual functions of the light guide and the light diffusion so that the line light source can be converted into the area source and the light is uniform and soft. Because the light guide plate of the utility model possesses the diffusion film, the light guide plate possesses the light diffusion function and a traditional diffusion plate can be avoided to be used. Because the cost of the diffusion film is lower than the cost of the traditional diffusion plate, by using the light guide plate of the utility model, the cost can be reduced. The diffusion film is firmly adhered to the light guide plate so that other fixed modes are not needed. The adhesion is firm and a structure is simplified.
