ABSTRACT:
The present invention provides an optical element capable of keeping the accuracy even in the case of use in an optical device such as an image display apparatus, without the risk of fluctuation of the optical characteristics even in the case a load is applied at the time of being assembled in the optical device. In order to achieve the object, an optical element comprising a supporting member, and an optical functional layer of a polymerizable liquid crystal material hardened on the supporting member with a predetermined liquid crystal regularity, wherein the optical functional layer has a 20 or more Vickers hardness value, is provided.
