ABSTRACT:
An AC plasma display includes a plurality of parallel column electrodes (14); a plurality of parallel row electrodes (21) disposed from, and perpendicular to, the column electrodes (14); a dielectric layer (17) for forming a wall charge is made of a low dielectric constant glass having a low melting point includes sodium oxide and boron oxide and covers the column electrodes (14); and an electrode protective layer (16) made from an inorganic material, for example silicon dioxide, prevents diffusion of sodium from the dielectric layer (17) to the column electrode (14). The dielectric layer (17) is made of a glass having a low dielectric constant of 8 or less to reduce pixel capacitance thereby reducing the electrical power consumption of the display.
