Abstract
(EN)
An input device according to one embodiment of the present invention is provided with a surface substrate, an optically isotropic support substrate arranged facing the surface substrate and having a lager thermal expansion coefficient than the surface substrate, a plurality of electrode parts supported by the support substrate, an intermediate substrate provided between the surface substrate and the support substrate, a first adhesive resin layer provided between the surface substrate and the intermediate substrate, and a second adhesive resin layer provided between the intermediate substrate and the support substrate. As the thickness of the first adhesive resin layer is 50 μm or greater, it is possible to visually recognize a display image correctly and maintain high reliability for a long period even when the surface substrate and a sensor unit significantly differing in material properties are used.

Selon un mode de réalisation, la présente invention concerne un dispositif d'entrée qui est pourvu d'un substrat de surface, d'un substrat de support optiquement isotrope disposé en face du substrat de surface et ayant un coefficient de dilatation thermique supérieur à celui du substrat de surface, d'une pluralité de parties d'électrode supportées par le substrat de support, un substrat intermédiaire disposé entre le substrat de surface et le substrat de support, d'une première couche de résine adhésive disposée entre le substrat de surface et le substrat intermédiaire, et d'une seconde couche de résine adhésive disposée entre le substrat intermédiaire et le substrat de support. Étant donné que l'épaisseur de la première couche de résine adhésive est supérieure ou égale à 50 µm, il est possible de reconnaître visuellement une image d'affichage correctement et de maintenir une fiabilité élevée pendant une longue période même lorsque le substrat de surface et une unité de capteur qui diffère de manière significative des propriétés matérielles sont utilisés.
