To provide a composition for an alignment layer, which is applicable to a plastics support material and forms the alignment layer superior in adhesion to an optical function layer (liquid crystal layer) and which is used to cause a liquid crystalline compound in the liquid crystal layer to be easily aligned by its alignment control force by rubbing treatment of the surface of the alignment layer and which forms the alignment layer being superior in adhesion to a support material and in durability and to provide a method of manufacturing an optical element using the same.
The composition for the alignment layer is used for manufacturing an optical element comprising a plastics support material 1, an alignment layer 2, and a one or more-layered optical function layer 3 consisting of the liquid crystalline compound and contains at least a nonionic water-soluble etherificated polysaccharides (A) and water and/or a lower alcoholic solvent (B). Hydroxyethyl cellulose, hydroxypropylmethyl cellulose, or methyl cellulose may be used as the nonionic water-soluble etherificated polysaccharides.
