    Abstract: An object of the present invention is to provide a polarizer with a high degree of alignment and an image display device including the polarizer. The polarizer of the present invention is a polarizer which is formed of a polarizer-forming composition containing a liquid crystal compound, a first dichroic material, and a second dichroic material, in which the first dichroic material and the second dichroic material are aligned horizontally with respect to a surface of the polarizer, the first dichroic material is a compound compatible with the liquid crystal compound, and the second dichroic material is a compound which is not compatible with the liquid crystal compound.

    Abstract: The present invention provides: a laminate which has excellent moisture-heat resistance and includes a light-absorbing anisotropic layer sandwiched between pressure sensitive adhesive layers; and an image display device using the same. The laminate includes a pressure sensitive adhesive layer, a light-absorbing anisotropic layer, and a pressure sensitive adhesive layer in this order, in which the light-absorbing anisotropic layer contains an organic dichroic substance, a thickness of the light-absorbing anisotropic layer is 5 μm or less, the pressure sensitive adhesive layer and the pressure sensitive adhesive layer are each a pressure sensitive adhesive layer at a closest position as viewed from the light-absorbing anisotropic layer in the laminate, and H represented by Expression (I) is 10.0 or less. H=(thickness of pressure sensitive adhesive layer+thickness of pressure sensitive adhesive layer)/total thickness of layers on inner side than pressure sensitive adhesive layer and pressure sensitive adhesive layer.
