Abstract: front page image
(EN) The problem addressed by the present invention is to provide a transparent film through which a background without color unevenness can be observed when the transparent film is not irradiated with light, a transparent screen using this transparent film, an image display system, and a transparent poster. The problem is addressed by a transparent film that has a support body, a dot arrangement formed from a two-dimensional arrangement of dots formed by fixing a cholesteric liquid crystal phase on the surface of the support body, and an overcoat layer laminated on the support body so as to cover the dots, wherein the surface area and spacing of the dots are made irregular.
(FR) La présente invention vise à fournir un film transparent à travers lequel un arrière-plan sans irrégularité de couleur peut être observé quand le film transparent n'est pas éclairé par de la lumière, un écran transparent utilisant ce film transparent, un système d'affichage d'images et une affiche transparente. Le film transparent comporte un corps de support, un agencement de points formé à partir d'un agencement bidimensionnel de points formés par la fixation d'une phase de cristaux liquides cholestériques sur la surface du corps de support, et une couche de finition stratifiée sur le corps de support de manière à recouvrir les points, la superficie et l'espacement des points étant rendus irréguliers.
(JA) 光を照射されない状態で、色ムラの無い背景を観察可能な透明フィルム、この透明フィルムを利用する透明スクリーンおよび画像表示システム、ならびに、透明ポスターの提供を課題とする。支持体と、支持体の表面にコレステリック液晶相を固定してなるドットを二次元的に配列してなるドット配列と、ドットを覆って支持体に積層されるオーバーコート層を有し、ドットの面積と間隔を、不規則にすることで、課題を解決する。
