  • Publication number: 20040246391
    Abstract: A flat-panel projection display comprises a slab waveguide having a preferably embossed diffraction grating on one face, a lens for directing light into an edge of the waveguide, and in the focal plane of the lens a liquid-crystal modulator for modulating the intensity of the light as a function of lateral position and elevational direction of travel. The light is ejected from the slab waveguide by the grating at angles corresponding to the input angles, giving a virtual display. The light from the modulator can be expanded in one dimension by passing through a magnifying waveguide, followed by scattering in the plane by a screen and projection by a lens at the other end of the waveguide. Head-up and 3-D displays can be constructed using this principle.

  • Publication number: 20040246424
    Abstract: The generation of residues or flakes of a color filter is suppressed to eliminate conduction failures on an LCD substrate having a color filter on an array substrate. A passivation film formed between a pixel electrode formed in each of a plurality of pixel regions and a TFT for driving the pixel electrode has a multi-layer structure constituted by SiN layers and a SiO layers, and the SiO layer is located at the top of the film. A resin CF layer is formed on the passivation film having such a multi-layer structure. Since the resin CF layer is formed directly on the SiO layer, reduction of the adhesion of the same is suppressed. As a result, the color filter is unlikely to come off when the resin CF layer is formed, and residues of the color filter is unlikely to be generated when a contact hole is formed in the resin CF layer. This suppresses conduction failures and makes it possible to provide a reliable TFT substrate and LCD having high display characteristics.

    Abstract: It is an object of the invention to suppress product development costs and reduce in size by reducing the LSI-mounting area as small as possible of a liquid crystal display device attached with two or more LCDs. Transparent pixel electrodes of LCDs 3 and 13 are connected to each other in series via a FPC 9, and the transparent pixel electrodes of the LCDs 3 and 13 are electrically connected to a single LSI 7 of a circuit board portion 8 provided on a soft conductive connecting member. Therefore, the circuit board portion 8 and the FPC 9 can be reduced in size by being bent, thus the LCDs 3 and 13 can be used as display portions of a portable telephone or the like.
