(EN) ANTI-GLARE SHEET FOR IMAGE DISPLAY DEVICE
(FR) FEUILLE ANTIREFLET POUR DISPOSITIF D'AFFICHAGE D'IMAGE

Abstract
(EN) An anti-glare sheet that exhibits excellent glossy black textures, blackness in dark locations, and anti-glare properties for dynamic images, and that is suited to the implementation of high quality images. The anti-glare sheet has, on at least one surface of a transparent substrate, an anti-glare layer comprising binder resin, diffusion particles, and binder particulates. The anti-glare sheet is characterized by the anti-glare layer having protrusions and recesses on the surface on the opposite side thereof to the transparent substrate, the protrusions and recesses being formed by protrusions based on agglomerations of the diffusion particles and/or diffusion particles having in the vicinity thereof a localized layer in which the density of binder particulates is high, and equation (1) and equation (2) being satisfied where Q is the luminance in the direction of regular transmission when visible light is perpendicularly irradiated on the anti-glare sheet from the transparent substrate side, Q30 is the luminance in a direction 30 degrees from regular transmission; and U is the average value of the transmission intensity obtained by respectively extrapolating, to a regular transmission, a straight line joining the luminance in a direction +2 degrees from regular transmission to the luminance in a direction +1 degree from regular transmission, and a straight line joining the luminance in a direction -2 degrees from regular transmission to the luminance in a direction -1 degree from regular transmission. Equation (1): 10<Q/U<36 Equation (2): Log10(Q30/Q)<-6
(FR) La présente invention porte sur une feuille antireflet qui présente d'excellentes textures de noir brillant, un excellent contraste dans des endroits sombres et d'excellentes propriétés antireflets pour des images dynamiques, et qui est appropriée à la mise en œuvre d'images de qualité élevée. La feuille antireflet a, sur au moins une surface d'un substrat transparent, une couche antireflet comprenant une résine de liant, des particules de diffusion et des particules de liant. La feuille antireflet est caractérisée en ce que la couche antireflet a des saillies et des renfoncements sur la surface sur le côté de celle-ci opposé au substrat transparent, les saillies et les renfoncements étant formés par des saillies basées sur des agglomérations des particules de diffusion et/ou des particules de diffusion ayant au voisinage de celles-ci une couche localisée dans laquelle la densité de particules de liant est élevée, et l'équation (1) et l'équation (2) sont satisfaites, dans lesquelles Q est la luminescence dans la direction d'émission régulière lorsqu'une lumière visible est irradiée perpendiculairement sur la feuille antireflet depuis le côté substrat transparent, Q30 est la luminance dans une direction à 30 degrés par rapport à une émission régulière, et U est la valeur moyenne de l'intensité d'émission obtenue par extrapolation, respectivement, par rapport à une émission régulière, d'une ligne droite reliant la luminance dans une direction de +2 degrés par rapport à une émission régulière à la luminance dans une direction de +1 degré par rapport à une émission régulière, et d'une ligne droite reliant la luminance dans une direction -2 degrés par rapport à une émission régulière à la luminance dans une direction -1 degré par rapport à une émission régulière.
