PRODUCTION OF LIGHT CONTROL PLATE

摘要

PURPOSE:To obtain a light control plate which is provided with various regions varying in scattering angle range by projecting light from a 1st wire-shaped irradiation source to one region of the plural regions on the surface of a film- like body consisting of a resin compsn. and projecting light of the 2nd wire- shaped irradiation source from a different angle to the other regions thereby curing the resin compsn. CONSTITUTION:The film-like body 3 consisting of the resin compsn. contg. at least 2 kinds of photopolymerizable oligomers or monomers having a difference in refractive index is formed and the surface of the film-like body 3 is divided to plural regions. The light from the wire-shaped irradiation source 1 is projected on at least one region and the light from the wire-shaped irradiation source 1 is projected on at least one other region from the different angle to cure the region by projection of the light from a spot light source or the collimated beams of light and projection of the diffused light or application of heat. The various regions different in the scattering angle range are thereby provided to the film-like body.
