Title (EN) OPTICAL FILM AND ITS PRODUCTION METHOD, POLARIZER AND LIQUID CRYSTAL DISPLAY DEVICE
(FR) FILM OPTIQUE ET SON PROCÉDÉ DE PRODUCTION, POLARISEUR ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
Abstract: front page image
(EN)An optical film having an acrylic resin layer and a cellulose acylate layer, wherein the weight-average molecular weight of the acrylic resin used as the main ingredient in the acrylic resin layer is from 600,000 to 4,000,000, hardly causes display unevenness when it is incorporated in a liquid crystal display device.
(FR)L'invention porte sur un film optique ayant une couche de résine acrylique et une couche d'acylate de cellulose, la masse moléculaire moyenne en poids de la résine acrylique utilisée comme ingrédient principal dans la couche de résine acrylique étant de 600 000 à 4 000 000, qui ne provoque guère d'irrégularités d'affichage lorsqu'il est incorporé dans un dispositif d'affichage à cristaux liquides.
