<P>PROBLEM TO BE SOLVED: To provide a polarization separating film through which a large quantity of p-waves is transmitted, an illuminator for a liquid crystal display element, of which the rate of p-waves contained in emitted light is large, and a liquid crystal display device with high luminance. <P>SOLUTION: The polarization separating film 10 has a film base material 12, and niobium oxide layers 14 formed on both faces of the film base material 12. The illuminator for the liquid crystal display element is equipped with a light guide plate, a light source arranged on the side face of the light guide plate, the polarization separating film disposed on the light emission side of the light guide plate, and a light reflection body disposed opposite to the polarization separating film with the light guide plate interposed in between. The liquid crystal display device is equipped with the liquid crystal display element, and the illuminator for the liquid crystal display element disposed on the rear face side of the liquid crystal display element. <P>COPYRIGHT: (C)2007,JPO&INPIT |
