An illumination device and a liquid crystal display device

摘要

A liquid crystal display device comprising a direct viewing type liquid crystal display element disposed between a front side polarizing sheet and a back side polarizing sheet, and an edge light type illumination device comprising a light guide, a light source, and a light reflecting means, characterized by a polarized light separator being disposed between said light guide and said liquid crystal display element wherein a first polarized light component is transmitted by said polarized light separator and at least a portion of second polarized light component is converted into said first polarized light component by said reflecting means and further comprising a light defector disposed in an optical path for deflecting the light ray emitted from said light guide to be substantially perpendicular to said liquid crystal display element. <IMAGE>
