Method of manufacturing information display device

An information display device has an information display plate where at least one or more kinds of particles are sealed between cells formed by a partition wall, the cells being between two opposite substrates at least either of which is transparent. At least either of electrodes is provided on a substrate, and an electric field is applied to the particles by the electrodes to move the particles, causing information such as an image to be displayed on the display plate. The surfaces of the substrates are smoothed by making D&#x2267;2H satisfied, with D being the diameter of a particle (a particle forming the particles), H the height of the electrodes. This thins the electrodes as much as possible (making the height of the electrodes small) and smoothes the surfaces of the substrates, and as a result, the information display device after an endurance test has an improved contrast ratio.

A light shielding blade material is provided for an optical apparatus and has at least three prepreg sheets each being comprised of an epoxy resin of a thermosetting type as a matrix resin and containing a fiber drawn in an alignment direction within the matrix resin. These prepreg sheets are superposed upon each other so that the alignment directions of the fibers of the prepreg sheets disposed adjacent to each other cross at right angles to each other. The material has also two or more films each being comprised of an epoxy resin of a non-cured state as a base resin and containing 15 to 40 weight % of carbon black in the epoxy resin. These films are disposed to form a laminate of the prepreg sheets and the films so that the prepreg sheets contact one surface or both surfaces of each film. The laminate is applied with pressure and heat to cure the epoxy resin, such that the epoxy resin constituting the base resin of the film is diffused and integrated into the matrix resin of the prepreg sheet so that an interface between the base resin and the matrix resin disappears, and that the carbon black is dispersed from the base resin of the film to the matrix resin of the prepreg sheet.

Manufacturing method of light shielding blade material

A light shielding blade material for use in an optical apparatus is constructed by a substrate composed of a plastic film having a pair of surfaces opposed to each other. A shield coating capable of blocking an incident light is formed on each surface of the substrate. A reinforcement member is disposed on each shield coating. The reinforcement member is composed of a thermosetting resin prepreg sheet reinforced with fibers arranged in an alignment direction, and hardened to laminate with the substrate through the shield coating. A lubricant coating having a black appearance and a lubricity sufficient to suppress a surface friction is formed on each reinforcement member such that an upper layer of the lubricant coating and a lower layer of the shield coating are separated from each other by an intermediate layer of the reinforcement member.
