Abstract

The invention relates to a plasma picture screen provided with a phosphor layer (9) which comprises a mixed particle mixture of a standard phosphor and a further phosphor which emits the same color. The use of two phosphors in one phosphor layer (9) renders it possible for undesirable properties of the phosphors to cancel each other out.
