Abstract
(EN)
The present invention relates to a liquid crystal film. An exemplary liquid crystal film can be used as a reflective polarizer for improving the optical use efficiency and luminance of a display device, such as an LCD, etc.
(FR)
La présente invention porte sur un film à cristaux liquides. Un film à cristaux liquides à titre d'exemple peut être utilisé en tant que polariseur réfléchissant pour améliorer l'efficacité d'utilisation optique et la luminance d'un dispositif d'affichage, tel qu'un dispositif d'affichage à cristaux liquides (LCD), etc..
(KO)
본 발명은 액정 필름에 관한 것이다. 예시적인 액정 필름은, 예를 들면, LCD 등의 디스플레이 장치의 광 이용 효율을 개선하고, 휘도를 향상시킬 수 있는 반사형 편광판으로 사용될 수 있다.
