Abstract
The present disclosure relates to the field of display technology, and provides a light guiding film. The light guiding film includes a plurality of prism bodies arranged as an array. Each of the plurality of prism bodies has a first surface and a second surface oppositely disposed. The first surface is a light exiting surface. A space is disposed between two adjacent prism bodies. The prism body is configured to refract light incident into the space to form refracted light, such that the refracted light is totally reflected in the prism body to form total reflection light.
