Title (EN) OPTICAL FILM
(FR) FILM OPTIQUE
(JA) 光学フィルム
Abstract:
(EN) This optical film 100 has a protective film 50 and a liquid crystal layer 30. A region 30a that is a part of the liquid crystal layer 30 has the same liquid crystal material as another region 30b, but the region 30a has a different alignment state from the other region 30b. An uneven pattern 60 having diffractive properties may be provided on the lower surface of the liquid crystal layer 30. Thus, it is possible to easily manufacture an optical film having an excellent design without causing damage to the liquid crystal layer.
(FR) Ce film optique 100 comprend un film de protection 50 et une couche de cristaux liquides 30. Une région 30a qui fait partie de la couche de cristaux liquides 30 possède le même matériau de cristaux liquides qu'une autre région 30b, mais la région 30a présente un état d'alignement différent de l'autre région 30b. Un motif irrégulier 60 ayant des propriétés de diffraction peut être disposé sur la surface inférieure de la couche de cristaux liquides 30. Ainsi, il est possible de fabriquer facilement un film optique ayant une excellente conception sans endommager la couche de cristaux liquides.
(JA) 光学フィルム100は、保護フィルム50と液晶層30を有する。液晶層30の一部の領域30aの液晶材料と他の領域30bの液晶材料が同一であり且つ一部の領域30aの液晶材料と他の領域の液晶材料30bとは、配向状態が異なる。液晶層30の下面に回折能を示す凹凸パターン60を設けてもよい。液晶層にダメージを与えることなく簡易に製造することができる、意匠性に優れた光学フィルムが提供される。
