A brighter and whiter reflector provides high reflection efficiency over a wide range of angles. An indenting tool is pressed against the surface of a matrix base material; the pressing operation is repeated while changing the position of the indenting tool on the surface of the base material for the matrix to successively form many pits, the inner surfaces of which are shaped like partial spheres, on the mold surface of the matrix base material so as to provide it as the matrix for forming the reflector. Then, a transfer mold having a mold surface which has a reversed pattern of the pits and projections of the mold surface of the matrix is made, and the mold surface of the transfer mold is transferred to the surface of the base material for the reflector to provide a reflector (1). Pits (4) of the reflector (1) are formed so that the depths the pits (4) range from 0.1 &mgr;m to 3 &mgr;m, the tilt angles of the inner surfaces of the pits (4) are distributed in the range of −18 degrees to +18 degrees, and the pitches between adjoining pits (4) range from 5 &mgr;m to 50 &mgr;m. A reflection type liquid crystal display device in accordance with the present invention is equipped with the reflector (1).
摘要:
A plurality of reflectors respectively having the same rough reflecting surfaces are formed substantially simultaneously on a transparent substrate of a large area. A photosensitive resin film is formed on a surface of a transparent substrate. An embossing die having a rough working surface is pressed against a photosensitive resin part of the photosensitive resin film and the photosensitive resin part is irradiated with ultraviolet rays from below the transparent substrate to form a prehardened photosensitive resin part. Those steps are repeated to form a plurality of prehardened, embossed photosensitive resin parts on the transparent substrate, and then parts not prehardened of the photosensitive resin film are removed by etching. The prehardened, embossed photosensitive resin parts are heated for hardening, and a metal reflecting film is formed on the hardened embossed photosensitive resin parts to complete a plurality of reflectors.
摘要:
This invention relates to a source material for vapor deposition, which is useful for forming a magnesium oxide thin film by vacuum vapor deposition process, and to a method of forming a transparent barrier film by using the magnesium oxide source material. The source material is composed of a magnesium oxide having a bulk density of 2.5 g/ml or more. This magnesium oxide can be obtained by sintering or fusing magnesium oxide material. For producing a transparent barrier film having a gas barrier property, this magnesium oxide is vapor-deposited on a surface of a transparent plastic base film by means of vacuum vapor deposition. The volume shrinkage or cracking of the evaporation source material can be avoided, thereby stabilizing the evaporation and prolonging duration of the evaporation. Further, it is possible to utilize a high power of electron beam. Since the evaporation source material is substantially free from pore, the evacuation of gas from the evaporation apparatus can be finished within a short period of time, and the vacuum degree within the evaporation apparatus can be stabilized. Since there is no splash or scattering during the evaporation., a transparent barrier film which is uniform in thickness and free from pinhole can be obtained.

A liquid crystal display includes a pair of substrates and a liquid crystal composition sealed between the substrates. The liquid crystal composition has a twist angle set within a range of 180-300 degrees and a retardation set within a range of 0.45-0.7 .mu.m wherein when an electric field is applied, the liquid crystal display is in a dark state, while when the electrid field is not applied, the liquid crystal display is in a bright state. A dichromatic coloring matter is contained in the liquid crystal composition, and it has a hue complementary to that of an image color of the liquid-crystal display in the bright state.
