Abstract
An optical film and a display device are provided. The optical film includes: multiple optical structures, wherein one side of each optical structure away from a display surface is provided with multiple arced surfaces for reflecting at least a portion of environment light, and each optical structure has a first refractive index; and a filling part being filled between the optical structures and having a second refractive index greater than the first refractive index. Adjusting curvatures of the arced surfaces can implement the adjustment of the angle of reflection to the environment light.
