Abstract
A light guide film for use with a light source includes a light-transmissive substrate and a light-transmissive layer. The substrate includes a top surface, and a light-incident lateral surface adapted to be disposed adjacent to the light source. The layer is disposed on the top surface of the substrate and has a light-incident lateral surface aligned with the light-incident lateral surface of the substrate. The light-transmissive layer has an inclined surface that is opposite to the substrate and that extends away from the light-incident lateral surface of the layer and obliquely toward the top surface of the substrate. The layer has a refractive index different from that of the substrate.
