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. |
