Abstract
(EN)
A polarizing plate and a display device. The polarizing plate (10) comprises: a support protective film (100) having a large refractive index and provided with a plurality of projecting structures (101), part of the surface of the projecting structure (101) being curved; and an optical compensation film (200) having a small refractive index, the optical compensation film (200) being provided with grooves (210) matching the plurality of projecting structures (101).
(FR)
L'invention concerne une plaque de polarisation et un dispositif d'affichage. La plaque de polarisation (10) comprend : un film protecteur de support (100) ayant un indice de réfraction élevé et pourvu d'une pluralité de structures en saillie (101), une partie de la surface de la structure en saillie (101) étant incurvée ; et un film de compensation optique (200) ayant un faible indice de réfraction, le film de compensation optique (200) étant pourvu de rainures (210) correspondant à la pluralité de structures en saillie (101).
(ZH)
一种偏光板及显示装置,偏光板(10)包括:折射率较大且开设有多个凸起结构(101)的支撑保护膜(100),凸起结构(101)的部分表面为曲面;折射率较小的光学补偿膜(200);光学补偿膜(200)开设有多个与凸起结构(101)相配合的凹槽(210)。
