PURPOSE: A plasma picture screen with increased efficiency is provided to have the advantage that no interactions between plasma and luminescent material take place, because the layer containing a luminescent material is no longer located in the plasma cells. CONSTITUTION: A plasma picture screen includes a front plate(1) comprising a transparent plate(3) on which a first dielectric layer(4) and a first protective layer(5) are applied, a carrier plate(2), a ribbed structure(11) which divides the area between the front plate(1) and the carrier plate(2) into plasma cells which are filled with a gas, and one or more electrode arrays(6,7,9) on the front plate(1) and the carrier plate(2) for the generation of corona discharges in the plasma cells. UV light with a wavelength of >172 nm is generated. The front plate(1) has a first layer containing a luminescent material on the side facing the plasma cells.
