Abstract
The present invention relates to a back light module and a liquid crystal display device using the same. The back light module includes a light source and a light guide plate, the light guide plate includes a light emitting surface, a bottom surface opposing the light emitting surface, a plurality of side surfaces joining the above two surfaces and a plurality of diffusing units which are the same size and arrange on the bottom surface. Wherein, at least one of the side surfaces is light incident surface and the light source is arranged beside the light incident surface, the pitch of the diffusing units is distributed on the bottom surface by a special function relating with the reciprocal of the distance between the corresponding diffusing unit and the light source. The present invention improves the evenness of luminance of the back light module and the performance of the liquid crystal display device using the same.
