Photoconductive switching element, photo-writing type recording medium, and their production method and utilization

A method for producing a photo-writing type recording medium for AC-driving system, which comprises

• forming a charge-generating material-containing lower charge generation layer, a charge-transporting material-containing charge transport layer, and a charge-generating material-containing upper charge generation layer in that order to form a photoconductive switching layer on the surface of an electrode layer formed on a substrate, wherein each of the lower charge generation layer, the charge transport layer and the upper charge generation layer is formed by the use of a solvent system comprising a solvent capable of swelling or dissolving the layer just below the coating layer,
• forming a display element layer on the surface of the transparent electrode layer of a transparent substrate having the transparent electrode layer formed thereon, and
• laminating the thus-obtained two substrates in such a manner that the photoconductive switching layer and the display element layer could face each other.
