Claim:
1. A method of manufacturing a polarizing plate, comprising: stretching and dyeing a laminate including a resin substrate having a long shape and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate, to thereby produce a polarizing film on the resin substrate; laminating an optically functional film on a side of the polarizing film of the laminate, to thereby produce an optically functional film laminate; and cutting widthwise direction end portions of the optically functional film laminate, and releasing the resin substrate from the polarizing film after the cutting, wherein the cut portions comprise the resin substrate, the polarizing film, and the optically functional film, wherein the polarizing film has a thickness of up to 10 μm, and the polarizing film is thin relative to the resin substrate.
