Process for producing light control plate having light-scattering pervious region

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.
