Abstract:
(EN) This liquid crystal element is provided with: a pair of substrates that are disposed to face each other; electrodes that are disposed on the opposed surfaces of the pair of substrates; a liquid crystal layer which is interposed between the pair of substrates and which is formed by curing a liquid crystal composition comprising liquid crystal and a polymerizable compound; and a liquid crystal alignment film that is formed on the surfaces on which the electrodes are disposed. The polymerizable compound contains a monofunctional (meth)acrylate compound, a polyfunctional (meth)acrylate compound, and the like. The liquid crystal alignment film is formed using a liquid crystal aligning agent containing a polymer component. The liquid crystal aligning agent contains at least one type of compound which is selected from the group consisting of silane compounds and polysiloxanes and in which the content ratio of a structural unit derived from a monomer having a specific side-chain structure is 10 mol% or less with respect to the total amount of all structural units of the polymer component.
(FR) Cet élément à cristaux liquides comporte : une paire de substrats qui sont disposés l'un en face de l'autre; des électrodes qui sont disposées sur les surfaces opposées de la paire de substrats; une couche de cristaux liquides qui est interposée entre la paire de substrats et qui est formée par durcissement d'une composition de cristaux liquides comprenant un cristal liquide et un composé polymérisable; et un film d'alignement de cristaux liquides qui est formé sur les surfaces sur lesquelles les électrodes sont disposées. Le composé polymérisable contient un composé (méth) acrylate monofonctionnel, un composé (méth) acrylate polyfonctionnel et similaire. Le film d'alignement de cristaux liquides est formé à l'aide d'un agent d'alignement de cristaux liquides contenant un composant polymère. L'agent d'alignement de cristaux liquides contient au moins un type de composé qui est choisi dans le groupe constitué de composés de silane et de polysiloxanes et dans lequel le rapport de teneur d'une unité structurelle dérivée d'un monomère ayant une structure de chaîne latérale spécifique est de 10 % en moles ou moins par rapport à la quantité totale de toutes les unités structurales du composant polymère.
(JA) 液晶素子は、対向配置された一対の基材と、一対の基材において互いに対向する面に配置された電極と、一対の基材間に配置され、液晶及び重合性化合物を含む液晶組成物を硬化させて形成された液晶層と、電極配置面上に形成された液晶配向膜とを備える。重合性化合物は、単官能(メタ)アクリレート化合物、多官能(メタ)アクリレート化合物等を含有する。液晶配向膜は、重合体成分を含有する液晶配向剤を用いて形成されてなる。液晶配向剤は、特定の側鎖構造を有する単量体に由来する構造単位の含有割合が、重合体成分の全構造単位の合計量に対し10モル%以下であり、かつシラン化合物及びポリシロキサンよりなる群から選ばれる少なくとも一種の化合物を含有する。
