Abstract

The dielectric layers in AC plasma display panel(AC PDP) are essential to the discharge cell structure, because they protect metal electrodes from sputtering by positive ion bombarding in discharge plasma and form a sheath of wall charges which are essential to memory function of AC PDP. This layer should have high dielectric strength and also be transparent because the luminance of PDP is strongly correlated this layer. In this paper, we discussed the dielectric strength and transparency of the dielectric layer under various conditions. As a result, on the $15{\mu}m$ thickness, the minimum dielectric strength was $29V/{\mu}m$ and the transmittance coefficient was about 80% after $570^{\circ}C$ firing process. It can be proposed that the resonable dielectric thickness in AC PDP is $15{\mu}m$ because it has about 80V margin on the maximum applied voltage.
