Abstract:
A laminate in which the occurrence of cracks is suppressed, and a laminate with a pressure-sensitive adhesive layer, a polarizing plate, and an image display device which use the laminate. The laminate includes a first optically anisotropic layer; and a second optically anisotropic layer, the first optically anisotropic layer and the second optically anisotropic layer being laminated directly or through an alignment film, in which the first optically anisotropic layer satisfies Expression (A) nx>ny, the second optically anisotropic layer satisfies Expression (B) nx 1.0, Expression (4) −40 nm≤Rth(550)≤70 nm, and Expression (5) Rth(550)
