Abstract
Provided is a laminate, which has a polarizer and an optically anisotropic layer and is excellent in thermal durability, and an organic electroluminescent device and a liquid crystal display device, which include the laminate. The laminate has two substrates and a polarizing plate disposed between the two substrates, in which the polarizing plate has a polarizer and an optically anisotropic layer, the polarizer contains a polyvinyl alcohol-based resin, the optically anisotropic layer is formed of a composition containing a polymerizable liquid crystal compound represented by General Formula (I): L1-G1-D1-Ar-D2-G2-L2, a moisture permeability of the substrate is 10−3 g/m2·day or less, and a water content of the polarizing plate is 3.0 g/m2 or less.
