Abstract
(EN)
The present invention provides a dimming device that is highly optically transmissive in a transmittance mode. A dimming film according to the present invention includes a first substrate having a first transparent electrode layer, a dimming layer that changes the scattering conditions of the transmitted light depending on whether a voltage is applied, and a second substrate having a second transparent electrode layer in that order. The dimming film is configured to switch between a non-scattering mode and a scattering mode depending on the scattering condition of the transmitted light. A haze ratio, which is a ratio of the haze of dimming film in a scattering mode to the haze of dimming film in a non-scattering mode (haze value in the scattering mode / haze value in the non-scattering mode), is 8.0 or greater, and the optical transmittance of the dimming film in the non-transmittance mode is 80% or greater.

La présente invention concerne un dispositif de gradation qui est hautement transmissif optiquement en mode de transmittance. Un film de gradation selon la présente invention comprend un premier substrat ayant une première couche d'électrode transparente, une couche de gradation qui change les conditions de diffusion de la lumière transmise selon qu'une tension est appliquée, et un second substrat ayant une seconde couche d'électrode transparente dans cet ordre. Le film de gradation est configuré pour commuter entre un mode de non-diffusion et un mode de diffusion en fonction de l'état de diffusion de la lumière transmise. Un rapport de trouble, qui est un rapport du trouble du film de gradation dans un mode de diffusion au trouble du film de gradation dans un mode de non-diffusion (valeur de trouble dans le mode de diffusion / valeur de trouble dans le mode de non-diffusion), est de 8,0 ou plus, et la transmittance optique du film de gradation dans le mode de non-transmittance est de 80 % ou plus.
