The invention concerns a panel comprising an electroluminescent organic layer and a photoconductive layer, having sandwiched between said two layers, an intermediate layer of electrodes electrically insulated from one another. The cells of said panel are provided with memory effect which makes them particularly simple to operate; preferably, during the addressing phases, compensation operations are used. By using the openings in an intermediate opaque layer or by using semi-transparent intermediate electrodes, it is possible to adapt simply and economically, at each cell, optical coupling between the electroluminescent layer and the photoconductive layer.
