| description | This image display body is obtained by sandwiching a display function layer with two transparent substrates. The display function layer contains liquid crystals, a photoisomerization material, and a transparent resin. The image display body switches between a light transmission state and a light scattering state depending on the alignment state of the liquid crystals. The photoisomerization material contains an azobenzene compound represented by structural formula (1), and as a result, the photoisomerization material absorbs little visible light and can suppress the reduction in color reproducibility of displayed images. In the structural formula (1), R represents an alkyl group and * represents a binding site.
L'invention concerne un corps d'affichage d'image qui est obtenu en prenant en sandwich une couche de fonction d'affichage avec deux substrats transparents. La couche de fonction d'affichage contient des cristaux liquides, un matériau de photoisomérisation et une résine transparente. Le corps d'affichage d'image commute entre un état de transmission de lumière et un état de diffusion de lumière en fonction de l'état d'alignement des cristaux liquides. Le matériau de photoisomérisation contient un composé azobenzène représenté par la formule structurale (1), et en conséquence, le matériau de photoisomérisation absorbe peu de lumière visible et peut supprimer la réduction de la reproductibilité de couleur d'images affichées. Dans la formule structurale (1), R représente un groupe alkyle et * représente un site de liaison.
本発明の画像表示体は、２つの透明基板で表示機能層を挟持して成り、上記表示機能層が、液晶と光異性化材料と透明樹脂とを含有し、上記液晶の配向状態によって光透過状態と光散乱状態とに切り替わる画像表示体である。 そして、上記光異性化材料が、下記構造式（１）で表されるアゾベンゼン化合物を含むこととしたため、光異性化材料の可視光域の吸収が少なく、表示される画像の色再現性の低下を抑制できる。 但し、構造式（１）中、Ｒはアルキル基を表し、＊は結合部位を表す。 |
