Document Type and Number:

WIPO Patent Application WO/2024/024409

Kind Code:

A1

Abstract:

This laminate comprises: a phase difference plate including a transparent substrate and a liquid crystal layer formed on the transparent substrate; and an adhesive layer for adhering the phase difference plate to a curved surface of a three-dimensional structure. If the storage modulus of the adhesive layer is E (MPa) and the thickness of the adhesive layer is T (μm), α as defined by the following equation (1) is 0.26-0.55 MPa, and T is 22-110 μm. (1): α=E×exp(E/T)
