In a plasma display panel, red, green, and blue pixels have the same voltage range for write discharges. The red, the green, and the blue pixels have first, second, and third data electrodes, respectively, covered with an insulating film. A red fluorescent substance layer is formed on the insulating film over the first data electrode. A green fluorescent substance layer is formed on the insulating film over the second data electrode. A blue fluorescent substance layer is formed on the insulating film over the third data electrode. The green fluorescent substance is smaller than both of the red and the blue fluorescent substance layers in thickness.

Plasma display panel capable of being easily driven and definitely displaying picture

A drive circuit for a plasma display panel is provided. A region of a plurality of surface discharge electrode pairs is divided such that the electrostatic capacitance between the surface discharge electrode pairs is divided into 2.sup.n equal portions (where n is a natural number). 2.sup.n-1 series resonant circuits are formed by the capacitances of two each of the divided surface discharge electrode pair regions, a coil, and a plurality of switches. A first voltage state and a second voltage state between the plurality of surface discharge electrode pairs are shifted by the series resonant circuit.

Plasma display panel drive circuit provided with series resonant circuits

The scan electrodes are divided into a plurality of groups. These scan electrode groups are divided into those of a scan period and those of a non-scan period in a writing discharge period. A compensation pulse is applied, without application of a scan base pulse, to the electrodes in the non-scan period. Thus it makes possible to suppress electromigration between scan and sustaining electrodes while securing light intensity of emission as in the prior art by using the same techniques as therein.
