The present invention relates to a method for manufacturing a polariser and a polariser manufactured using the same, the method comprising, in a method for manufacturing a polariser, the steps of: a) immersing a polyvinyl alcohol-based film in an aqueous solution containing an azo-based dye having an absorption wavelength of 300nm to 550nm so as to swell the same; b) dyeing the swollen polyvinyl alcohol-based film using an iodine-based dye; and c) stretching the dyed polyvinyl alcohol-based film. La présente invention concerne un procédé de fabrication d'un polariseur et un polariseur fabriqué à l'aide de celui-ci, le procédé comprenant, dans un procédé de fabrication d'un polariseur, les étapes : a) d'immersion d'un film à base d'alcool polyvinylique dans une solution aqueuse contenant un colorant azoïque ayant une longueur d'onde d'absorption de 300 nm à 550 nm de manière à gonfler celui-ci ; b) de coloration du film à base d'alcool polyvinylique gonflé à l'aide d'un colorant à base d'iode ; et c) d'étirage du film à base d'alcool polyvinylique teint. 본 발명은 편광자 제조 방법에 있어서, a) 폴리비닐알코올계 필름을 300nm 내지 550nm의 흡수파장을 갖는 아조계 염료를 포함하는 수용액에 침지하여 팽윤하는 단계; b) 팽윤된 폴리비닐알코올계 필름을 요오드계 염료로 염착하는 단계; 및 c) 상기 염착된 폴리비닐알코올계 필름을 연신하는 단계를 포함하는 편광자 제조 방법 및 이를 이용하여 제조된 편광자에 관한 것이다.
