Illuminating apparatus providing polarized color light and display apparatus including the same

摘要

Provided are an illuminating apparatus providing polarized color light and a display apparatus including the illuminating apparatus. The illuminating apparatus includes a light source (100); a polarization light guide plate unit (200) converting a polarization direction of light emitted from the light source into linearly polarized light, and collimating the light; and a cholesteric liquid crystal color filter (30) disposed on an upper portion of the polarization light guide plate unit to selectively reflect light according to a polarized status and a wavelength of light.
