Abstract:
(EN) Provided is a structure having high display contrast. Also provided are a transparent display and an illumination device that use the structure and a light source. Further provided are a liquid crystal display device and an information display device equipped with the transparent display, the illumination device, and a transparent image display panel. The structure includes: a pair of transparent substrates with an electrode formed on at least one of the substrates; an electro-optical layer sandwiched between the transparent substrates; and a transparent plate laminated on at least one of the transparent substrates with an optical bonding layer in between. The application of a voltage allows the electro-optical layer to control the transmission state or diffusion state of incident light. A transmittance at a measured angle calculated by the following Formula 3 is 60% or more in the transmission state of the incident light. The transparent plate has an average internal transmittance of 80% or more in a wavelength region of 400 nm to 700 nm in an optical path length of 50 mm. (Measured angle = arcsin (refractive index of the medium at the portion excluding optical bonding layer adjacent to transparent plate / refractive index of transparent plate) Formula 3).
(FR) L’invention concerne une structure ayant un contraste d’affichage élevé. Elle concerne également un dispositif d’affichage transparent et un dispositif d’éclairage qui utilisent la structure et une source de lumière. Elle concerne aussi un dispositif d’affichage à cristaux liquides et un dispositif d’affichage d’informations équipés du dispositif d’affichage transparent, du dispositif d’éclairage et d’un panneau d’affichage d’image transparent. La structure comprend : une paire de substrats transparents avec une électrode formée sur au moins l’un des substrats ; une couche électro-optique prise en sandwich entre les substrats transparents ; et une plaque transparente appliquée en couche sur au moins un des substrats transparents, avec une couche optique de collage entre eux. L’application d’une tension électrique permet à la couche électro-optique de commander l’état de transmission ou l’état de diffusion de la lumière incidente. Un facteur de transmission à un angle mesuré, calculé par la Formule 3 suivante, est de 60 % ou plus dans l’état de transmission de la lumière incidente. La plaque transparente a un facteur de transmission interne moyen de 80 % ou plus dans une région de longueurs d’onde allant de 400 nm à 700 nm dans une longueur de trajet optique de 50 mm. (Angle mesuré = arcsin (indice de réfraction du milieu au niveau de la partie excluant la couche optique de collage adjacente à la plaque transparente / indice de réfraction de la plaque transparente) Formule 3).
(JA) 本発明は、表示コントラストが高い構造体を提供する。また、前記した構造体と光源とを利用した透明ディスプレイ、照明装置を提供する。さらに、前記した透明ディスプレイ、照明装置と透明画像表示パネルを備えた液晶表示装置、情報表示装置を提供する。 少なくとも一方に電極が形成されている一対の透明基板と、透明基板間に挟持されている電気光学機能層と、透明基板の少なくとも一方に、光学接合層を介して積層されている透明板とを有し、電気光学機能層は、電圧の印加により入射光を透過する状態と散乱する状態とを制御でき、入射光を透過する状態において、下記式3の測定角度の透過率が60%以上であり、透明板は、光路長が50mmでの波長400nm~700nmにおける波長域で平均内部透過率が80%以上である構造体。 (測定角度=arcsin(透明板と隣接する光学接合層以外の部の媒体の屈折率/透明板の屈折率) 式3。)
