Provided are a polarizer protection film, a polarizing plate including same, and a display device including the polarizing plate. For the polarizer protection film, when a refractive index of an in-plane slow axis direction is defined as nx and a refractive index of an in-plane fast axis direction is defined as ny, the range of the value nx-ny is from approximately 0 to approximately less than 0.01. L'invention concerne un film de protection de polariseur, une plaque de polarisation le comprenant, et un dispositif d'affichage comprenant la plaque de polarisation. Pour le film de protection de polariseur, lorsqu'un indice de réfraction d'une direction d'axe lent dans le plan est défini par nx et qu'un indice de réfraction d'une direction d'axe rapide dans le plan est défini par ny, la plage de la valeur nx-ny est d'approximativement 0 à approximativement moins de 0,01. 편광자 보호 필름, 이를 포함하는 편광판, 상기 편광판을 포함하는 표시 장치가 제공된다. 편광자 보호 필름은 편광자 보호 필름의 면내의 지상축 방향의 굴절률을 nx, 면내의 진상축 방향의 굴절률을 ny라 정의할 경우, nx-ny값의 범위가 약 0 내지 약 0.01미만의 범위이다.
