POLYESTER FILM COMPOSITE, LIGHT DIFFUSER PLATE, AND UTILIZATION THEREOF

摘要

A polyester film composite material comprising a biaxially oriented polyester film having a thickness of at least 50 mu m but not more than 200 mu m and an easy-adhesion coating applied onto one or each surface thereof, and having a haze value of less than 2 % and a total light transmissivity of at least 90 %, and a light-diffusing plate comprising a light-diffusing layer laminated on the surface of the easy-adhesion coating thereof. According to the present invention, a light-diffusing plate having excellent optical properties when used in a liquid crystal display and a substrate therefor are provided.
