Abstract
The present invention discloses an anti-peep film, a method for manufacturing the same and a display device. The anti-peep film includes a main body and at least one light converging structure provided inside the main body; a refractive index of the main body is different from a refractive index of the light converging structure, to cause incident light to be outputted after being converged by the light converging structure. In the anti-peep film, the method for manufacturing the same and the display device provided by the present invention, a light converging structure is located inside a main body, and a refractive index of the main body is different from a refractive index of the light converging structure, to cause incident light to be outputted after being converged by the light converging structure, such that the display device has good anti-peep properties in all the different viewing directions.
