Abstract

The invention discloses a reflector plate, a backlight module and a display device. The reflector plate is composed of a plurality of reflecting bowls arranged in an array mode. The reflection bowl cup comprises a bottom plate, a shielding cover plate and an annular side wall, and an assembly opening is formed in the center of the bottom plate; the shielding cover plate is parallel to the bottom plate and right faces the assembly opening. The side face of the shielding cover plate extends to form a connecting strip, and the connecting strip is bent towards the assembling opening and connected with the bottom plate. The shielding cover plate, the connecting strip and the bottom plate are combined to form an assembling groove, and the assembling groove is used for covering a light-emitting part of the backlight module; the annular side wall is connected with the bottom plate; the annular side wall is arranged around the outer edge of the bottom plate to form a trumpet-shaped light emitting channel which surrounds the shielding cover plate; in addition, a light outlet is formed in the end, away from the bottom plate, of the annular side wall, and the light outlet is rectangular. The front face of the light-emitting part is shielded, light can only be emitted to the bottom plate and the annular side wall in the lateral direction and is finally reflected to the light outlet to form a rectangular light spot so as to be matched with pixels of the rectangular partition, and the halo problem is solved.
