摘要:
A process for producing a light control plate, which comprises(1) preparing an assembly composed of a film of a photopolymerizing composition and a light pervious body having a light scattering pervious pattern arranged along the surface of the film and (2) irradiating light to the assembly from that side of the assembly on which the light pervious body exists, thereby to polymerize the photopolymerizable composition of the film and to form a light control plate having a light pervious region through which light advances straightforwardly defined by the light scattering pervious pattern.
摘要:
A method of producing a light control plate which induces scattering of light at different angles of incidence for different places. The method comprises (1) preparing an assembly comprising a film of a photo-polymerizable composition and a light-pervious body having a light-impervious pattern arranged along the surface of the film, (2) irradiating light limitedly to the assembly from that side where the light-pervious body at a limited angle while moving the assembly continuously in the planar direction of the film thereby to polymerize at least part of the photopolymerizable film, the light being emitted from a first linear light source whose long axis is positioned in a direction crossing the moving direction of the assembly; and thereafter (3) polymerizing the photopolymerizable composition of that portion of the film-like molded article which is covered with the light-impervious pattern of the light-pervious body by light irradiation or heating.

A filter for a liquid crystal display device, having a light diffusing plate which is obtained by forming a composition in the form of a film which contains at least two photopolymerizable oligomers or monomers having refractive indexes which differ from each other by at least 0.01 and irradiating UV light on the composition. When the filter is fitted to a light emitting side of a liquid crystal display device, an angle of view of the liquid crystal display face plane is widened, shadows due to opaque parts of the device are reduced, and a Moire fringe is hardly formed.
