ABSTRACT:
A liquid crystal optical device is comprised of a pair of substrates having respective inner major surfaces spaced apart from one another and a liquid crystal layer composed of liquid crystal molecules and interposed between the spaced inner major surfaces. An electrode layer is disposed on at least one of the inner major surfaces. An organic filter layer colored in a given color tone is electrodeposited on the electrode layer. An organic alignment layer is disposed on the filter layer in contact with the liquid crystal layer for aligning the liquid crystal molecules. An organic protective layer is interposed between the alignment layer and filter layer for adhesively securing the alignment layer to the filter layer to protect the alignment layer from stress applied thereto relative to the filter layer.
