Polarizing plate and method for producing same, and optical film material

Abstract

The present invention provides a polarizing plate that includes a polarizer, and an optical film including an alignment layer, an optically anisotropic layer, and an optically isotropic acrylic polymer layer on at least one surface of the polarizer, in which the optically anisotropic layer is a layer formed by irradiating a polymerizable composition including a liquid crystal compound that is directly applied to the alignment layer with light to polymerize the liquid crystal compound, the acrylic polymer layer is a layer formed by curing a polymerizable composition including (meth)acrylate that is directly applied to a surface of the layer formed from the polymerizable composition including a liquid crystal compound, and the thickness of the acrylic polymer layer is larger than the thickness of the optically anisotropic layer. According to the present invention, it is possible to provide a polarizing plate having a small thickness.
