Abrégé
(EN)
The present invention relates to a luminance-enhanced film, and more particularly, to a luminance-enhanced film in which islands-in-the-sea yarns with birefringence are included in a base material, thus significantly lowering production costs and also rapidly improving luminance. The luminance-enhanced film of the present invention includes a birefringent islands-in-the-sea yarn within a base material. Accordingly, unlike a conventional stack type luminance-enhanced film, a luminance enhancement effect is excellent while not forming a number of layers. Further, since several hundreds of layers are not formed in one film, fabrication is very convenient and production costs can be saved greatly.

La présente invention concerne un film à luminance améliorée, et plus particulièrement, un film à luminance améliorée dans lequel des fils obtenus par la technique « islands-in-the-sea » (îles dans la mer) et présentant une biréfringence sont compris dans un matériau de base, abaissant ainsi significativement les coûts de production et améliorant également rapidement la luminance. Le film à luminance améliorée de la présente invention comprend un fil biréfringent obtenu par la technique « islands-in-the-sea » dans un matériau de base. En conséquence, contrairement à un film classique à luminance améliorée de type à empilement, l’effet d’amélioration de la luminance est excellent bien qu’un certain nombre de couches ne soit pas formé. En outre, étant donné que plusieurs centaines de couches ne sont pas formées dans un film, la fabrication est très commode et les coûts de production peuvent être grandement réduits.
