Abstract

L'invention concerne un élément PDLC scellé avec un film de protection de surface ayant une couche d'étanchéité sur une surface d'extrémité de celui-ci, dans lequel le film de protection de surface peut être décollé sans résidu de la couche d'étanchéité restant sur la surface d'extrémité de l'élément PDLC.　Cet élément de commande de lumière scellé avec un film de protection de surface comprend : un élément de commande de lumière comprenant un premier film conducteur transparent, un second film conducteur transparent qui est disposé de façon à s'opposer au premier film conducteur transparent, et une couche de cristaux liquides dispersés dans un polymère qui est disposée entre le premier film conducteur transparent et le second film conducteur transparent ; un film de protection de surface comprenant un substrat et une couche adhésive disposée sur un côté du substrat, le film de protection de surface étant stratifié par l'intermédiaire de la couche adhésive sur au moins l'une des surfaces primaires de l'élément de commande de lumière ; et une couche d'étanchéité qui est disposée sur une surface d'extrémité de l'élément de commande de lumière et du film de protection de surface. Si l'épaisseur de la couche d'étanchéité est a (μｍ), l'épaisseur du substrat du film de protection de surface est b (μｍ), et l'épaisseur de l'élément de commande de lumière est c (μｍ), toutes les relations suivantes (1) à (3) sont satisfaites. a<0,3c (1) 10<b<150 (2) a<0,4b (3)
