The addressing time should be reduced by modifying cell structure and/or driving method in order to replace the dual scan system by single scan and increase the luminance in large ac plasma display panel(PDP). In this paper, the effects of the addressing time was decreased with decreasing thickness of dielectric layer on the front glass and thickness of white dielectric layer on the rear glass. the decreasing rate were 160ns/10$mu extrm{m}$ and 270ns/10$mu extrm{m}$, respectively Also in case of decreasing the height of barrier rib, addressing time was decreased at the rate of Sons/10$mu extrm{m}$.
