Abstract:
(EN) Provided are a polarizing plate and a liquid crystal display device including same, the polarizing plate including a polarization film, a contrast-improving layer, and an anti-reflection film that are sequentially laminated. The minimum reflectance of the anti-reflection film is no greater than 0.45%. The anti-reflection film has a first substrate layer, a high-refraction layer and a low-refraction layer that are laminated in order from the contrast-improving layer. The contrast-improving layer includes a first resin layer and a second resin layer facing the first resin layer. The second resin layer is provided with a pattern part having optical patterns and a flat part between the optical patterns. The pattern part satisfies Equation 1 and the optical patterns have a base angle (θ) of 75° to 90°. The slope of the reflectance of the polarization plate in Equation 2 is no greater than 0.3.
(FR) La présente invention se rapporte à une plaque de polarisation, et à un dispositif d'affichage à cristaux liquides comprenant cette plaque. Ladite plaque de polarisation inclut un film polarisant, une couche d'amélioration de dynamique de contraste et un film antireflet qui sont stratifiés de manière séquentielle. Le facteur de réflexion minimal du film antireflet est inférieur ou égal à 0,45 %. Ce film antireflet a une première couche de substrat, une couche à réfraction élevée et une couche à faible réfraction qui sont stratifiées dans l'ordre à partir de la couche d'amélioration de dynamique de contraste. Ladite couche d'amélioration de dynamique de contraste inclut une première couche de résine et une seconde couche de résine qui fait face à la première couche de résine, la seconde couche de résine étant pourvue d'une partie à motifs ayant des motifs optiques et d'une partie plate entre les motifs optiques, la partie à motifs étant conforme à l'équation 1 et les motifs optiques ayant un angle de base (θ) de 75° à 90°. La pente du facteur de réflexion de la plaque de polarisation dans l'équation 2 est inférieure ou égale à 0,3.
