Summary:PROBLEM TO BE SOLVED: To provide a polarizer which exhibits both high transmission and high polarization, i.e., high white luminance and high display contrast, and also provide a method of manufacturing the same.SOLUTION: The method of manufacturing the polarizer at least comprises a swelling process, a dyeing process, a crosslinking process, and an extending process which are applied to a polyvinyl alcohol film. In the swelling process, the polyvinyl alcohol film is extended by a factor of 1.4 to 2.4, thereby controlling the degree of crystallinity of the polyvinyl alcohol film to be 25 to 32%.
