It is an object of this invention to increase the stability of the quantum well structure of laminar perovskite compounds having excellent optical characteristics and possible applications in light emitting elements. In this invention, it was discovered that amines having an unsaturated bond can be introduced into the organic layer of organic-inorganic laminar perovskite compounds comprising a metal halide and an organic amine, and the organic layer can be polymerized by applying external energy such as by irradiating with UV light or radiation. In this way, the quantum well structure is stabilized. This invention is an organic-inorganic laminar perovskite polymer compound produced by cross-linking unsaturated bonds of an organic-inorganic laminar perovskite compound represented by the general formula (RNH3)2MX4 (in the formula, R is a hydrocarbon group having an unsaturated bond, X is a halogen or mixture of same, M is Group IVa metal, Eu, Cd, Cu, Fe, Mn or Pd). R is represented by CH3(CH2)n C.ident.C-C.ident.CCH2 (n = 2-14). It is preferred that M is Pb, and X is a bromine atom.
