ABSTRACT:
A flexible light guiding film includes a base film having a substantially constant thickness, and a light controlling portion disposed on the base film. Edges of the light controlling portion and the base film are coplanar and define a light incident surface of the light guiding film. The light incident surface is thicker than the base film, but has a similar thickness with that of a light exiting surface of a light source.
