Abstract

A plasma picture screen, in particular an AC plasma picture screen with a coplanar arrangement having an enhanced luminance. A UV light emitting layer (8) is provided on the front plate (1), which comprises a glass plate (3) on which a dielectric layer (4) and a protective layer (5) are provided, or on the carrier plate (2) with the phosphor (10). The layer (8) comprises a VUV phosphor which converts the VUV light of the plasma discharge into UV light with a wavelength between 200 and 350 nm and emits this in the direction of the phosphor layer (10).
