    Abstract: In a long-gap discharge using a trigger discharge in a display cell of a PDP having three electrodes (X, Y, A), a technology capable of stably generating the trigger discharge with low power consumption by using a float electrode is provided. In a dielectric layer of the PDP, a long gap is formed between first and second display electrodes, first and second float electrodes which are capacitive-coupled to the first and second display electrodes are formed, and a short gap is formed between the first and second float electrodes. A sustain pulse is applied to the first and second display electrodes, thereby generating a small trigger discharge in the short gap. Subsequently to this discharge, a main discharge at the long gap is generated. Electrodes and capacitances are structured so that the main discharge has an intensity equal to or smaller than one-fifth of an intensity of the trigger discharge.
