Beschreibung
Zusammenfassung:	Provided is an illumination system for a flat panel display device. The illumination system includes: a light source; a light guide plate allowing light generated from the light source to be incident through a side to propagate and made of an optically isotropic material; a upper layer disposed on a top surface of the light guide plate and made of an optically anisotropic material having two different refractive indices, one of which is the same as the refractive index of the light guide plate; and a polarization selection emitting structure which is formed at an interface of the light guide plate and the upper layer and in which different polarization components in perpendicular directions are refracted, reflected, diffracted, or scattered to different degrees.
