Abstract

PURPOSE: To impart an even polarization ability to the polarization layer by using the transparent or semi-transparent resin material layer having light transmittance or diffusive transmittance and the adhesive material layer having light diffusive transmittance including transparent or semi-transparent particles.
CONSTITUTION: The semi-transparent resin material layer 1 comprising applying fine undulations 12 to the photo detecting surface of a polyester film 11 and the polarizing layer 3 comprising affixing triacetate films 32, 32' as protection covering to both surfaces of the polarizer 31 comprising adsorbing and orienting polarizing elements on a polyvinyl alcohol base film are affixed together by way of an adhesive material layer 2 comprising arraying transparent or semitransparent TiO2-coated mica 21 in laminar form. The particles such as the abovementioned TiO2-coated mica 21 are preferably flake form in shape and mean particle sizes thereof are preferably 3 to 150μ and the thickness thereof about 0.1 times the mean size or under. The contents of the abovementioned particles in the abovementioned adhesive material layer are desirably 3 to 60wt%.
