Abstract
A display device for producing polychromatic luminous images comprising a display panel containing gas cells, electrodes for ionization of the gas, and a photoconductive layer located between the electrodes and responsive to a scanning invisible radiating beam. Each cell further comprises luminophore emitting primary visible radiations at the time of ionization of the gas, the ionization being effected by rendering the photoconductive layer locally conductive.
