Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical switching element to improve display characteristics and driving power by dissolving restrictions on a CGL application solvent so as to easily fabricate a dual CGL structure and to suppress asymmetry of electrical response characteristics in the dual CGL structure and an optical writing type display medium using the element. SOLUTION: The optical switching element has an optical switching layer which comprises a pair of charge generation layers and a charge transport layer interposed between the pair of charge generation layers, wherein the charge transport layer contains a charge transport polymer with a predetermined structure.
