    Abstract: A plasma display unit comprises a pair of substrate glasses, discharge electrodes formed on inner surfaces of the substrate glasses, and a fluorescent member disposed between the substrate glasses for emitting light in response to the discharge of the electrode. Each substrate glass used in the plasma display unit essentially consists by weight of 50-65% SiO2, 2-15% Al2O3, 0-4% MgO, 0-2.9% CaO, 2-13% SrO, 0.5-13% BaO, 10-27% MgO+CaO+SrO+BaO, 0-1% Li2O, 2-10% Na2O, 2-13% K2O, 7-15% Li2+Na2O+K2O, 1-9% ZrO2, 0-5% TiO2, 0-1% Sb2O3, and 0-1% As2O3. The substrate glass exhibits small thermal contraction even if subjected to heat treatment at a temperature of 570 DEG C or more, has a coefficient of thermal expansion of 75-95 x 10 / DEG C, and is high in volume resistivity and excellent in chemical durability as compared with a soda lime glass.

    Abstract: In the provision of a color filter on a front plate comprising a substrate 1, electrodes (4, 5) provided on the substrate, a dielectric layer 6 provided on the electrodes, and a protective layer 7 provided on the dielectric layer, a specific color filter is provided on the substrate 1, between the electrode 5 and the first dielectric layer 6a, or between the first dielectric layer 6a and the second dielectric layer 6b, or between the second dielectric layer 6b and the protective layer 7. By virtue of this constitution, troubles, such as breaking or unacceptable shape of edge, are not caused in the formation of the electrodes.

    Abstract: The invention describes a plasma picture screen, in particular an AC plasma picture screen, with enhanced luminance. The front plate (1) comprises a glass plate (3) to which a dielectric layer (4), a UV-reflecting layer (8), and a protective layer (5) are applied. The UV-reflecting layer (8) shows a high reflection in the wavelength range of the plasma emission (>172 nm) and a high transmission in the visible wavelength range. The UV-reflecting layer (8) reflects UV light (12) emitted in the direction of the front plate (1) back towards the phosphors (10).
