The present invention is directed to the provision of a high-contrast display apparatus. The display apparatus of the present invention includes a light source, a display section having an electro-optical conversion device for transmitting or scattering light introduced from the light source, light control means for reflecting the light introduced from the light source at a prescribed reflection angle, and a light reflecting member for causing the light reflected by the light control means and transmitted through the electro-optical conversion device to be reflected outside the field of view of a viewer who is viewing the display section straight on.

Display apparatus with particular light control and light reflecting

In a display apparatus that has a polymer dispersed liquid crystal materialencapsulated in a gap between a completed first substrateand a completed second substrateby using a sealing memberand has a display region M and a peripheral region N in a region where the polymer dispersed liquid crystal materialis encapsulated, a wiring electrodehaving light shielding properties is provided in at least a part of the peripheral region N of the completed second substrate, and an ultraviolet ray transmitting portionthat transmits an ultraviolet ray therethrough is provided in the peripheral region where the wiring electrodeis provided. An ultraviolet ray is applied from the substrate side where the ultraviolet ray transmitting portionis provided to polymerize a monomer in the peripheral region N. The ultraviolet ray transmitting portion is formed of, e.g., a plurality of small holes, and the small holes are dispersedly arranged at equal intervals.

An object of the present invention is to provide a liquid crystal display apparatus that can eliminate brightness nonuniformity by suitably diffusing light emitted from a light source. The liquid crystal display apparatus includes a liquid crystal panel providing a liquid crystal between a pair of substrates, the liquid crystal panel having an effective display area for displaying information, a sealing member placed around the liquid crystal in order to seal the liquid crystal between the pair of substrates, a light source for illuminating the liquid crystal panel from an edge thereof, and light diffusing means, provided between the pair of substrates, for diffusing the light introduced from the light source into the effective display area.
