Abstract
(EN)
[Problem] To improve reliability of a light control cell, in which the transmittance is able to be changed by means of application of a voltage to electrodes, while effectively avoiding a short circuit of the electrodes. [Solution] A light control cell 20 according to the present invention comprises: a first substrate 30 that contains a first resin base material 32; a second substrate 40 that contains a second resin base material 42; a liquid crystal layer 55 that is arranged between the first substrate and the second substrate; and a sealing material 51 that is positioned between the first substrate 30 and the second substrate 40 and circumferentially surrounds the liquid crystal layer 55. At least one of the first substrate and the second substrate comprises the electrodes. At least a part of the peripheral edge of at least one of the substrates is positioned on the sealing material.

[Problème] L'invention a pour objet d'améliorer la fiabilité d'une cellule de commande de lumière, dans laquelle la transmittance est susceptible d'être modifiée au moyen de l'application d'une tension à des électrodes, tout en évitant efficacement un court-circuit des électrodes. [Solution] Une cellule 20 de commande de lumière selon la présente invention comporte: un premier substrat 30 qui contient un premier matériau de base en résine 32; un deuxième substrat 40 qui contient un deuxième matériau de base en résine 42; une couche 55 de cristaux liquides qui est disposée entre le premier substrat et le deuxième substrat; et un matériau 51 d'étanchéité qui est positionné entre le premier substrat 30 et le deuxième substrat 40 et entoure circonférentiellement la couche 55 de cristaux liquides. Au moins un des premier et deuxième substrats comporte les électrodes. Au moins une partie du bord périphérique d'au moins un des substrats est positionnée sur le matériau d'étanchéité.
