|Title:||OPTICAL FILM ASSEMBLY, BACKLIGHT MODULE, AND DISPLAY DEVICE|
An optical film assembly, a backlight module, and a display device, the backlight module comprising a light source (101) for emitting at least a first light ray; and a bonded first optical film (102) and a second optical film (103); the first optical film (102) comprises a stacked substrate (1021) and a function layer (102), the function layer (1022) being a diffusion film, a brightness enhancing film, a reflective film, or a prism film layer, and the second optical film (103) being a light conversion film, the light conversion film receiving the first light ray and converting same into at least a second light ray for emission, such that the emergent light angle of the backlight module matches the requirements for wide-angle display. The emergent light angle of the backlight module can be increased, such that the display device achieves a wide-angle effect.
