Abstract

L'invention porte sur un film optique pour une cellule à cristaux liquides en mode VA du type à multiples domaines, lequel film optique peut améliorer la luminance d'un affichage de blanc à un coût faible, sans diminuer la qualité d'affichage. Le film optique (10) est utilisé pour une cellule à cristaux liquides en mode VA du type à multiples domaines présentant un film de polymère transparent (11), un polariseur (12) et une couche de compensation optique (14) qui sont stratifiés dans cet ordre. Le film optique (10) inclut en outre une plaque λ/4 (13) qui est agencée entre le polariseur (12) et la couche de compensation optique (14). L'angle défini par un axe d'absorption du polariseur (12) et un axe de retard de la plaque λ/4 (13) est réglé dans une plage de 45 degrés plus/moins 5 degrés.
