Abstract
A curved surface backlight module and a curved surface display device are provided. The backlight module includes a plurality of light-emitting units. The light-emitting units include reflector cups. The plurality of reflector cups include first reflector cups located in an edge partition and second reflector cups located in a central partition. The first reflector cups are asymmetric with respect to a first curved surface normal corresponding to a position at where the first reflector cups are located. A maximum brightness center of the first reflectors of the edge partition can be made to emit light parallel to a user's viewing direction, and brightness attenuation at an edge of a display device can be relieved.
