Abstract

A plasma display device includes: a dielectric layer on which a plurality of through-holes of a dielectric layer is disposed in a matrix shape; upper and lower electrode layers formed at both upper and lower surfaces of the dielectric layer; upper and lower substrates disposed on the outer surface of the upper and lower electrode layers; and a third electrode layer having a plurality of third electrodes which are formed between the upper substrate and the upper electrode layer, or the lower substrate and the lower electrode layer, and are insulated from the upper and lower electrode layers. Accordingly, a plasma display device can be realized which has stability and efficiency of a micro discharge. In addition, each pixel can concurrently carry out a sustain discharge by applying an alternating voltage to upper and lower electrodes forming sustain electrodes.
