Abstract The dependence of front dielectric thickness on input power density, luminance, and luminous efficacy according to the voltage of the auxiliary pulse in an AC PDP with an auxiliary electrode was investigated. It was found that two important factors influencing the luminous efficacy due to variation of the front dielectric thickness. One is the range of the voltage of the auxiliary pulse within which the power density decreases, but the luminance slightly increases, which improve the luminous efficacy. The other is the transmittance reducing the luminance as front dielectric thickness increased, leading to a decrease in the luminous efficacy. In this work, considering these two factors, the luminous efficacy is maximized at a front dielectric layer thickness of 40μm.
