    摘要: Disclosed is a cellulose ester film which, when used in a polarizing plate, can impart excellent dimensional stability, curling properties and surface properties to the polarizing plate. Also disclosed is a light-scattering-film, a polarizing plate or a liquid crystal display element which is produced by using the cellulose ester film, and therefore has more excellent optical anisotropy, higher surface properties and a smoother surface, causes less curling, and has good surface quality. The cellulose ester film comprises 1 to 50% by mass (inclusive) of microparticles having an average particle diameter of 1 to 400 nm (inclusive) and a compound showing negative birefringence in the direction of drawing, and has a retardation value (R0) defined by the equation (I) of 0 to 5 nm (inclusive) and a retardation value (Rt) defined by the equation (II) of −10 to 20 nm (inclusive), both measured at 23° C. and 55% RH: Equation (I): R0=(nx−ny)×d; and Equation (II): Rt=[(nx+ny)/2×nz]×d.

    摘要: When an optical element is produced using a liquid crystal film having no supporting substrate film for the purpose of decreasing the weight, the liquid crystal film layer may often pose problems of fine wrinkly deformation of and cracking in a caused by strain occurring during a manufacturing/processing step. The present invention intends to provide an elliptical polarizer having a thinned optical anisotropic element which is free from such deformation and cracking. The elliptical polarizer of the present invention comprises at least a polarizer and an optical anisotropic element wherein said optical anisotropic element comprises a liquid crystalline substance layer with a fixed liquid crystal orientation, a tacky adhesive/adhesive layer, and a stress blocking layer.
