Abstract
A front light includes a light source, a light guide for receiving light from the light source through an end surface of the light guide and outputting the light through a first large surface which is substantially perpendicular to the end surface, and a polarization selecting section for selectively transmitting light having particular polarization, the polarization selecting section being attached to the first large surface of the light guide such that any reflection does not occur at an interface between the polarization selecting section and the light guide.
