    • The present invention provides an optical element capable of improving the adhesive property between a refractive index anisotropic layer and an alignment property providing layer for. providing alignment property to the refractive index anisotropic layer and further improving the endurance of each of the layers.An optical element 10 has an alignment property providing layer 12 laminated on a transparent base material 11 and a refractive index anisotropic layer 13 laminated on the layer 12. The layer 12 is an alignment layer having alignment limiting force for providing alignment property to the layer 13, and is made of an alignment layer composition capable of expressing the alignment limiting force. The layer 13 is a liquid crystal layer formed by curing (polymerizing) a liquid crystal composition comprising a polymerizable liquid crystal material. A monomer or oligomer having one or more functional groups, together with a polymer, is incorporated into the alignment layer composition. The monomer or oligomer in the layer 12 is crosslinked with molecules in the layer 13, which is adjacent to the layer 12, near the interface between the layers 12 and 13.
