ABSTRACT:
The invention provides an optical switching element and a device, an optically addressed type display medium and a display each including such an optical switching element. The optical switching element comprising an optical switching layer including lower and upper charge generating layers and a charge transporting layer sandwiched therebetween, wherein the optical switching element has at least one of the following characteristics. (1) In the charge transporting layer, a charge transporting material to binder polymer ratio calculated according to the formula: [charge transporting material/(charge transporting material+binder polymer)]×100 (% by weight) is 50% by weight or more; (2) a polymer compound is used as the charge transporting material; and (3) the charge generating layer on the light incident side (the lower charge generating layer) has a lower light absorptance than that of the other charge generating layer (the upper charge generating layer).
