1. A laminate comprising, in the following order:
a pressure sensitive adhesive layer 1;
a light-absorbing anisotropic layer;
a pressure sensitive adhesive layer 2; and
an optically anisotropic layer,
wherein 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 1 and the pressure sensitive adhesive layer 2 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 1+thickness of pressure sensitive adhesive layer 2)/total thickness of layers on inner side than pressure sensitive adhesive layer 1 and pressure sensitive adhesive layer 2  Expression (I).
