ABSTRACT:
An a.c. driving system photo-writing type recording medium having a substrate formed an electrode layer on one side thereof, a transparent substrate formed a transparent electrode layer on one side thereof, an optical switching layer having a pair of charge generation layers each including a charge generation material; and a charge transport layer including a charge transport material, disposed between the pair of charge generation layers, and a display element layer, in which the electrode layer of the substrate and the transparent electrode layer of the transparent substrate are opposed to each other, and the following equation (1) is satisfiedin-line-formulae description="In-line Formulae" end="lead"?|Ipcgl−Ipctl|≦0.5 eV (1)in-line-formulae description="In-line Formulae" end="tail"?where Ipcgl is an ionization potential of the charge generation material and Ipctl is an ionization potential of the charge transport material.
