Abstract:
1. A reflective plate of a liquid crystal display apparatus, comprising: a substrate; and a reflective layer disposed on the substrate for reflecting incident light, the reflective layer comprising a plurality of reflective sub-regions, each of the sub-regions having at least one reflective surface for reflecting the incident light, wherein the reflective surfaces are designed so that light reflected by the reflective surface forms a divergent pencil of rays, wherein all of the divergent pencils of rays substantially overlap to form a common light-emitted area at a predetermined distance from the substrate, and wherein the common light-emitted area is formed at a position such that a line, parallel with the normal of the reflective plate and passing through a center of the common light-emitted area, does not intersect the reflective plate.
