Abstract
The present disclosure discloses a backlight module and a display apparatus. A microprism film layer is further arranged on a light emitting side of a light guide plate, and the microprism film layer is located in a range of a preset distance by which the light guide plate extends from a side close to a light source to a side away from the light source; and the microprism film layer includes a plurality of first microprism structures, and the first microprism structures are configured to make an incident angle of light at a first interface when entering the first microprism structures greater than an emitting angle of the light at the first interface when exiting from the first microprism structures when the light in the light guide plate enters the first microprism structures from the light guide plate and then enters the light guide plate from the first microprism structures.
