ABSTRACT:
A polarized light emitting light guide plate includes: a transparent substrate of optically isotropic material, in which the light incident through a lateral side thereof travels; an anisotropic liquid crystal polymer layer formed on an upper surface of the substrate and having first and second refractive indices with respect to first and second perpendicular polarization components; and a polarization separation microstructure formed at an interface between the transparent substrate and the liquid crystal polymer layer, which refracts or reflects the first polarization component and transmits the second polarization component. The refractive index of the polarization separation microstructure is substantially equal to the refractive index of the substrate; the first refractive index of the liquid crystal polymer layer is greater than the refractive index of the substrate, and the second refractive index of the liquid crystal polymer layer light is substantially equal to the refractive index of the substrate.
