Light valve apparatus and display system using the same.

摘要

A light valve apparatus comprising: a light valve layer (33) for forming an optical image as changes of light scattering state; and two substrates (31, 32) between which said light valve layer (33) is gripped and at least one of which is transparent such that the following condition is satisfied: t >/= d DIVIDED 4 2ROOT n<2> - 1 where t denotes a central thickness of said at least one of said substrates (31, 32), n denotes a refractive index of said at least one of said substrates (31, 32) and d denotes a maximum diameter of an effective display area of said light valve layer (33).
