Title (EN) OPTICAL SHEET
(FR) FEUILLE OPTIQUE
Abstract: front page image
(EN)Disclosed is an optical sheet which is used in a liquid crystal display. The optical sheet is not readily damaged by external impact, and thus is easy to handle and can reduce failure rate, leading to a decrease in production cost and an increase in production efficiency. Also, it can prevent a decrease in brightness.
(FR)L'invention porte sur une feuille optique qui est utilisée dans un dispositif d'affichage à cristaux liquides. La feuille optique n'est pas facilement endommagée par un impact externe, ce qui la rend facile à manipuler et permet de réduire le taux d’échec, réduisant ainsi le coût de production tout en augmentant le rendement de production. Ladite feuille peut également empêcher une diminution de la brillance.
