Reflector plate capable of enlarging peripheral reflection area, backlight module and display device

The utility model relates to a reflector plate capable of enlarging peripheral reflection area, a backlight module and a display device, the reflector plate is provided with a plurality of through holes for a plurality of light-emitting parts to extend in, the reflector plate is also provided with a plurality of first reflection areas and a plurality of second reflection areas, and the second reflection areas are distributed on the periphery of the first reflection areas. The light-emitting parts are distributed in the first reflection areas and the second reflection areas, and the area of each second reflection area is larger than that of each first reflection area. Through the structural design of the reflector plate, the area of the peripheral area of the reflector plate can be increased, so that the light of the light-emitting part extends to the periphery after being reflected by the reflector plate, the brightness is further improved, and the uniformity of the whole area is optimized. 本实用新型涉及扩大外围反射面积的反射
