Abstract
A light guide film which is adapted for use with a light source has a light transmissive substrate and a light-transmissive member unit. The substrate has a light-exiting top surface, a bottom surface that is opposite to the top surface and a lateral surface that interconnects the top and bottom surfaces and that is adapted to face toward the light source. The member unit includes a bottom member that is disposed on the bottom surface of the substrate, and a lateral member that is connected to the lateral surface of the substrate and that is adapted to be disposed between the light source and the lateral surface of the substrate. The substrate has a refractive index which is less than that of the member unit.
