Abstract:
1. A method of manufacturing a polarizing plate, comprising: forming a laminate comprising a resin substrate and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate, then stretching and dyeing the laminate to produce a polarizing film on the resin substrate; laminating an optically functional film on the polarizing film on the resin substrate to produce an optically functional film laminate; and then peeling the resin substrate from the optically functional film laminate, wherein the peeling is performed so that an angle a is smaller than an angle β; wherein the angle α is formed between a surface of the optically functional film laminate immediately before the peeling and a peeling direction of the resin substrate, and wherein the angle β is formed between the surface of the optically functional film laminate immediately before the peeling and a peeling direction of the polarizing film, wherein the surface of the optically functional film laminate is the surface directly facing the resin substrate; and wherein the peeling direction of the resin substrate is substantially the same as the conveyance direction of the optically functional film laminate immediately before the peeling and the peeling direction of the polarizing film is the pulling direction.
