Abstract(in English) The most important problem for the DC-PDP is how to extend its life.We have earlier reported that it can be resolved by means of a resistor-in-cell panel with high gas pressure.We conducted theoretical studies on cathode sputtering,which determines the life,with regard to deterioration of the luminance and other characteristics.A two-dimensional cell model was adopted.Sputtered cathode atoms diffuse in accordance with the solution of a diffusion equation and deposit the cell walls.A stationary state solution is obtained.The luminance decay curve obtained from the solution agrees with the measured one.A theoretical expression of life in terms of the pressure and current is obtained from a sputtering rate study by Townes.This expression agrees qualitatively with the experiments.The theory is applied to the AC- PDP.
