  • OPTICAL MODULATING DISPALY DEVICE AND PRODUCTION METHOD THEREFOR AND DISPLAY APPARATUS MOUNTING THE OPTICAL MODULATING DISPLAY DEVICE THEREON
    Publication number: 20090213298
    Abstract: The present invention relates to an optical modulating display device (200) such as a liquid crystal displaying device provided with a front-light type planar illuminating device. The above front-light type planar illuminating device allows illuminating light to propagate inside a substrate (1), and is provided with a low refraction layer (3) being lower in refractive index than the substrate (1) and being in close contact with the inner surface of the substrate (1), and with reflection structure (11) on the outer surface of the substrate (1). The optical modulating display device (200) provided with the above front-light type planar illuminating device can ensure a sufficient amount of guide light propagating inside the substrate (1) and reduce non-uniformity in display illumination. And a display apparatus mounting the above optical modulating display device (200) thereon can be reduced in thickness and weight and provide a high quality display.
