Abstract
(EN)
The present invention addresses the problem of providing a layered body which includes a light absorption anisotropic layer, in which a decrease in degree of polarization is suppressed even when the layered body is stretched in a plurality of directions simultaneously, and an optical device and a display device which use the layered body. This layered body has at least a resin substrate and a light absorption anisotropic layer, the tan δ peak temperature of the resin substrate being 170°C or below, the light absorption anisotropic layer containing a crystalline compound and a dichroic substance, and the degree of orientation of the dichroic substance being 0.95 or greater.

Le problème de la présente invention concerne un corps stratifié qui comprend une couche anisotrope d'absorption de lumière, dans laquelle une diminution du degré de polarisation est supprimée, même lorsque le corps stratifié est étiré dans une pluralité de directions simultanément, et un dispositif optique et un dispositif d'affichage qui utilisent le corps stratifié. Ce corps stratifié comprend au moins un substrat de résine et une couche anisotrope d'absorption de lumière, la température de pic de tan δ du substrat de la résine étant de 170°C ou moins, la couche anisotrope d'absorption de lumière contenant un composé cristallin et une substance dichroïque et le degré d'orientation de la substance dichroïque étant de 0,95 ou plus.
