Title (EN) LIGHT CONTROL FILM
(FR) FILM ANTI-REFLET
(JA) 調光フィルム
Abstract: front page image
(EN) The purpose of the present invention is, in regards to a light control film, to more reliably shield transmitted light than prior art. A liquid crystal layer (8) is sandwiched between first and second laminate bodies (5D, 5U) wherein at least alignment layers (13, 17) are provided on base materials (6, 15) made of a transparent film material. The light distribution of the liquid crystal in the liquid crystal layer (8)is controlled by driving transparent electrodes (11, 16) provided at the first and second laminate bodies (5D, 5U), thereby controlling the transmission of light. The optical axes of the base materials (6, 15) of the first and second laminate bodies (5D, 5U) are orthogonal to each other.
(FR) L'objectif de la présente invention est, en ce qui concerne un film anti-reflet, de bloquer de manière plus fiable une lumière transmise que dans l'état de la technique. Une couche de cristaux liquides (8) est prise en sandwich entre un premier et un second corps stratifiés (5D, 5U) dans lesquels au moins des couches d'alignement (13, 17) sont disposées sur des matériaux de base (6, 15) constitués d'un matériau de film transparent. La distribution de lumière des cristaux liquides dans la couche de cristaux liquides (8) est commandée par des électrodes transparentes de commande (11, 16) disposées au niveau des première et seconds corps stratifiés (5D, 5U), ce qui permet de commander la transmission de la lumière. Les axes optiques des matériaux de base (6, 15) des premiers et secondes corps stratifiés (5D, 5U) sont orthogonaux l'un par rapport à l'autre.
(JA) 調光フィルムに関して、従来に比して一段と確実に透過光を遮光できるようにすることを目的とする。透明フィルム材による基材(6、15)に少なくとも配向層(13、17)を設けてなる第1及び第2の積層体(5D、5U)により液晶層(8)を挟持し、第1及び又は第2の積層体(5D、5U)に設けられた透明電極(11、16)の駆動により液晶層(8)に係る液晶の配光を制御して透過光を制御する。第1及び第2の積層体(5D、5U)の基材(6、15)の光軸が直交する。
