A light guiding film is provided including a main body, and a light diffusion structure comprising a plurality of micro concave lenses arranged in a first direction and a second direction to form a second dimensional array and the curvature of each concave lens and the junction of the concave lenses are different from zero. Light from a light source passes through the light diffusion structure and is refracted into the main body and then propagates in the main body by total reflection.
