Abstract: Each of the red, green and blue column electrodes has widened portions each having a row-direction width larger than that of the other portions. Each of the widened portions faces a head portion of each of the transparent electrodes of a pair of row electrodes constituting each row electrode pair. The widened portion of the green column electrode facing the green discharge cell provided with the green phosphor layer is located in a different position in the column direction from a position of each of the widened portions of the red and blue column electrodes respectively facing the red and blue discharge cells respectively provided with the red and blue phosphor layers.

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)BO3:Eu or the like which is a borate-system red phosphor and a second phosphor of Y(V, P)O4:Eu which is a phos-vana system red phosphor.

Abstract: For improvement in the performance of a PDP, a dielectric layer, deposited on the inner face of the front glass substrate of the PDP and covering row electrode pairs, is formed of a dielectric material having a relative dielectric constant of 9 or less, and a protective layer overlying the dielectric layer includes a magnesium oxide crystal causing a cathode-luminescence emission having a peak within a wavelength range of 200 nm to 300 nm upon excitation by electron beams, and discharge gas filling the discharge space includes 10% or more xenon by volume.
