Light guide plate, backlight source and display apparatus

Abstract

The present invention relates to the technical field of display, and discloses a light guide plate, a backlight source and a display apparatus, for solving the problem of the exit light non-uniformity of the backlight source. The light guide plate comprises a light guide plate main body and at least one boss, the light guide plate main body comprises a first light entrance surface, a first light exit surface intersecting with the first light entrance surface, and a first bottom surface opposed to the first light exit surface; the boss is located on the first light entrance surface and comprises a second bottom surface adjoining the first light entrance surface, a top surface opposed to the second bottom surface, as well as two end faces and two side surfaces respectively intersecting with the top surface and the second bottom surface at two ends, wherein the area of the top surface is less than that of the second bottom surface, the two end faces are respectively flush with the first bottom surface and the first light exit surface, and the two side surfaces are respectively slope surfaces which may be used as a second light entrance surface. The light guide plate mentioned by the present invention is used to improve the exit light uniformity of the backlight source.
