Abstract

A surface discharge plasma display apparatus comprising a plurality of pairs of column electrodes extending horizontally in parallel, and a plurality of row electrodes facing the column electrodes at a distance, said row electrodes extending perpendicularly to the column electrodes to define an emitting pixel region with the facing one pair of column electrodes, wherein at least one of the column electrodes in the pair comprises a base portion extending horizontally and a projecting portion extending perpendicularly from the base portion every emitting pixel region, wherein the length of the projecting portion is within the range from 400 μm to 1000 μm. In the surface discharge plasma display apparatus according to the present invention, the emitting efficiency is improved to increase the level thereof, the amount of the current which passes through each of the electrodes may be decreased, thereby the consumption power per emitting pixel region being decreased. Thus, the amount of the heat generated in a unit area of the plasma display apparatus may be decreased, so that the address failure of the emitting pixel region due to the generated heat may be prevented.
