摘要： A method for driving an AC type plasma display panel is provided in which time necessary for addressing can be shortened without deteriorating stability of a display. Before the addressing, a reset process is performed by applying an increasing waveform voltage between a reference potential line and a scan electrode so as to equalize charge in all cells. In the addressing, a selection voltage Vya1 having the same polarity as a final applied voltage Vyr2 in the reset process and an absolute value larger than the voltage Vyr2 by a potential difference &Dgr;Vy is applied between a scan electrode corresponding to a selected row and the reference potential line.

摘要： A display device (1) including a surface discharge type plasma display panel (2) performs an addressing operation, a sustain operation and a reset operation. In the addressing operation, address discharge of an opposed discharge form with the second electrode (Y) used as a cathode is generated between the second electrode (Y) and a third electrode (A) in a cell to be energized or in a cell not to be energized. In the reset operation, an obtuse wave pulse (Pr1) having a negative polarity is applied to the second electrode (Y) so as to generate charge adjustment discharge starting from discharge of the opposed discharge form with the second electrode (Y) used as a cathode between the second electrode (Y) and the third electrode (A).

摘要： A plasma display panel includes a pair of substrates forming a discharge space between the substrates, and lateral barrier ribs extending in a row direction and longitudinal barrier ribs extending in a column direction that divide the discharge space into cells. Each lateral barrier rib is divided into two portions in the column direction such that a vent passage is formed in the divided portion. In the plasma display panel, raised portions, which are lower than the lateral barrier ribs and connect the lateral barrier ribs divided into the two portions with each other, are formed in the vent passage.
