1. An optical laminate comprising in order:
a surface protective layer; a first pressure sensitive adhesive layer; a light absorption anisotropic layer; and a second pressure sensitive adhesive layer,
wherein an indentation elastic modulus of the first pressure sensitive adhesive layer is greater than an indentation elastic modulus of the light absorption anisotropic layer,
the light absorption anisotropic layer is a layer formed of a composition for forming a light absorption anisotropic layer containing a liquid crystal compound and a dichroic substance, and
a thickness of the light absorption anisotropic layer is less than 5 μm.
