DIFFUSIVE LAMINATE, MANUFACTURING METHOD OF DIRECTIVE DIFFUSER AND DIRECTIVE DIFFUSER

摘要

PPROBLEM TO BE SOLVED: To provide a diffusive laminate which reduces defects upon duplication by making it possible to perform the adhesion and release smoothly between an original plate and photosensitive material and is capable of manufacturing a directive diffuser having high diffusiveness by improving the diffusiveness of the original plate. PSOLUTION: In the diffusive laminate, relief processing is performed on one side surface of a film having no birefringence and a releasing layer, composed of a releasing agent and fillers which have refractive index different from that of the releasing agent and are dispersed in the releasing agent is laminated on the other side surface of the film. This invention also provides a manufacturing method of a directive diffuser using the diffusive laminate, and the directive diffuser. PCOPYRIGHT: (C)2007,JPO&INPIT
