Abstract:
A plasma screen comprising a front plate (1) which comprises a glass plate (3) on which a dielectric layer (4) and a protective layer (5) are deposited, comprising a carrier plate (2) coated with a fluorescent layer (11) having a rib structure (14), which divides the space between front plate (1) and carrier plate (2) in plasma cells which are filled with a gas, and comprising one or more electrode arrays (6, 7, 12) on the front plate (1) and the carrier plate (2) for generating silent electrical discharges in the plasma cells and comprising a structured black matrix (8) which is coated with a reflecting layer (9) between dielectric layer (4) and protective layer (5) on the side turned away from the viewer, said protective layer so formed and deposited over said black matrix and said reflecting layer so as to reduce undesired reactions of said black matrix and said reflecting layer with said dielectric layer.
