Abstract
Provided is a method for manufacturing a polarizing plate, comprising a step of irradiating an optical laminate with ultraviolet rays having an emission wavelength band of 380 nm to 410 nm. The optical laminate sequentially comprises a first base film, a first adhesive layer, a linear polarizer, a second adhesive layer, a second base film and a reverse dispersion liquid crystal layer. The first adhesive layer and the second adhesive layer each comprise a photosensitizer for initiating a curing reaction in a wavelength band of 350 nm to 410 nm, and the ultraviolet rays are irradiated on the first base film side of the optical laminate.
