Abstract
The present invention relates to a method of manufacturing a polarizer, including: preparing a polyvinyl alcohol-based polarizer dyed with one or more of iodine and dichromatic dyes; and forming a depolarization region having simple substance transmittance of 80% or more in a wavelength band of 400 nm to 800 nm by bringing a decoloring solution including 1 wt % to 30 wt % of a decolorant into local contact with some regions of the polarizer, and a polarizer manufactured using the same.
