Abstract
In a gas discharge display apparatus, a dielectric layer overlies the row electrode pairs provided between the opposing front and back glass substrates placed across the discharge space. A protective layer for the dielectric layer includes a crystalline MgO layer that has a property causing a cathode-luminescence emission having a peak within a wavelength range of 200 nm to 300 nm upon excitation by electron beams. A red phosphor layer generating visible light by being excited by vacuum ultraviolet light includes a mixed phosphor of a first phosphor of (Y, Gd)BO:Eu or the like which is a borate-system red phosphor and a second phosphor of Y(V, P)O:Eu which is a phos-vana system red phosphor.
