Abstract
(EN)
Provided are a polarizing plate and an optical display device including same, the polarizing plate comprising: an absorptive polarizer; and a first protection film and a reflective polarizing film which are sequentially stacked on the lower surface of the absorptive polarizer, wherein an axis having a low refractive index in the in-plane directions of the first protection film forms an angle of approximately -5° to +5° with respect to an axis having a high refractive index in the in-plane directions of the reflective polarizing film.
(FR)
L'invention concerne une plaque de polarisation et un dispositif d'affichage optique la comprenant, la plaque polarisante comprenant un polariseur absorbant ; et un premier film de protection et un film polarisant réfléchissant qui sont séquentiellement empilés sur la surface inférieure du polariseur absorbant, un axe ayant un faible indice de réfraction dans les directions dans le plan du premier film de protection formant un angle d'environ -5° à +5° par rapport à un axe ayant un indice de réfraction élevé dans les directions dans le plan du film polarisant réfléchissant.
(KO)
흡수형 편광자 및 상기 흡수형 편광자의 하부면에 순차적으로 적층된 제1보호 필름 및 반사형 편광 필름을 포함하고, 상기 제1 보호 필름의 면내 방향 중 굴절률이 낮은 축은 상기 반사형 편광 필름의 면내 방향 중 굴절률이 높은 축을 기준으로 약 -5° 내지 +5°의 각도를 이루는 것인, 편광판 및 이를 포함하는 광학표시장치가 제공된다.
