Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To prevent peeling or color change in a high temp. environment for a long period by laminating a polarizing plate having a cellulose acetate film as a protective layer with an adhesive layer to a reflector having through holes. SOLUTION: The polarizer of this polarizing plate contains uniaxially oriented polyvinylalcohol(PVA)-iodine complex or PVAdichroic dye as a dichroic material. Cellulose acetate films are laminated as protective layers on both surfaces of the polarizer. This polarizing plate is laminated with an adhesive layer to a reflector having through holes. The adhesive layer consists of an acryl copolymer. The holes formed in the reflector are preferably circular or square since the opening process of the holes is easy. The aperture area of one hole is preferably about 1 to 100μm<2> and more preferably about 5 to 50μm<2> . If the area is <1μm<2> , the gas produced by decomposition of the polarizing plate is hardly permeated, and if the area exceeds 100μm<2> , the through holes can be visually observed.
