(JA) 粉砕防止フィルムおよび該フィルムを備える表示デバイス
Abstract
(EN)
A shatter prevention film (206) that is affixed to a top glass (210) of a display device (201) having a polarizer (205), and serves as a shatter prevention film that can suppress the occurrence of a darkened field of view that occurs when wearing polarized eyewear while using equipment such as a portable device provided with a display device. The shatter prevention film (206) is provided with a light transmissive film (207), and an adhesive layer (209) disposed on one surface of the light transmissive film (207). The shape of the light transmissive film (207) is formed so that the angle of the molecular orientation axis of the resin of the light transmissive film (207) is 45±20° with respect to the transmission axis of the polarizer (205) of the display device (201) at the nearest position to the top glass (210).

L'invention concerne un film de prévention de brisement (206) qui est fixé sur un verre supérieur (210) d'un dispositif d'affichage (201) comprenant un polarisateur (205), et qui joue le rôle de film de prévention de brisement permettant de supprimer l'apparition d'un champ de vue assombri qui se produit lors du port de lunettes polarisées en utilisant un équipement comme un dispositif portable comportant un dispositif d'affichage. Le film de prévention de brisement (206) comprend un film transmettant la lumière (207), et une couche adhésive (209) disposée sur une surface du film transmettant la lumière (207). La forme du film transmettant la lumière (207) est telle que l'angle de l'axe d'orientation moléculaire de la résine du film transmettant la lumière (207) est de 45±20° par rapport à l'axe de transmission du polarisateur (205) du dispositif d'affichage (201) à la position la plus proche du verre supérieur (210).
