Abstract
(EN)
(Abstract) (Problem) To provide a polarizing plate capable of minimizing cracks in a recess. (Solution) A polarizing plate (1) is provided with a film-like polarizer (7) and at least a pair of optical films (5, 9) containing a resin; the polarizer (7) is placed between the pair of optical films (5, 9) and overlaps the pair of optical films (5, 9); a recess (2) is formed at the periphery (1p) of the polarizing plate (1); the end (7e) of the polarizer (7) along the recess (2) is located inside the periphery (1p) of the polarizing plate (1); and a resin layer (4) continuing from the pair of optical films (5, 9) is formed from the end (7e) of the polarizer (7) along the recess (2) to the periphery (1p) of the polarizing plate (1).

Le problème décrit par la présente invention est de fournir une plaque de polarisation capable de réduire au minimum les fissures dans un évidement. La solution de l'invention consiste en une plaque de polarisation (1) pourvue d'un polariseur de type film (7) et d'au moins une paire de films optiques (5, 9) contenant une résine ; le polariseur (7) est placé entre les deux films optiques (5, 9) et chevauche les deux films optiques (5, 9) ; un évidement (2) est formé à la périphérie (1p) de la plaque de polarisation (1) ; l'extrémité (7e) du polariseur (7) le long de l'évidement (2) est située à l'intérieur de la périphérie (1p) de la plaque de polarisation (1) ; et une couche de résine (4) dans la continuité des deux films optiques (5, 9) est formée à partir de l'extrémité (7e) du polariseur (7) le long de l'évidement (2) jusqu'à la périphérie (1p) de la plaque de polarisation (1).
