The present invention relates to a polarizing plate (100, 110) that includes a protective film (102) stacked on at least one surface, and the protective film (102) is stacked through an adhesive layer with antistatic performance, and the one surface of the polarizing plate (101) where the protective film (102) is stacked is subject to corona or plasma discharge treatment (103) to suppress generation of static electricity generated when the protective film (102) is peeled off from the polarizing plate (101) to minimize a foreign substance to be mixed, thereby decreasing a defect rate and increasing process efficiency. 본 발명은 적어도 일 면 상에 적층되는 보호필름(102)을 포함하고, 상기 보호필름(102)은 대전방지 성능이 부여된 점착제층을 통해 적층되며, 상기 보호필름(102)이 적층되는 측의 편광판(101)의 일 면은 코로나 또는 플라즈마 방전처리(103)됨으로써, 제조 공정 중 편광판(101)에서 보호필름(102) 박리 시 발생하는 정전기의 발생을 억제함으로써 이물(104)의 혼입을 최소화하여 불량률이 감소되고, 공정상의 효율이 향상된 편광판(100, 110)에 관한 것이다.
