PLASMA DISPLAY PANEL WITH ARC-SHAPED CATHODES

摘要

A direct current plasma display device (PDP) includes two plates and a plurality of parallel anodes and parallel cathodes arranged on an inner surface of two plates, respectively. Grooves of a predetermined depth are provided on the rear plate and metallic cathodes are formed on the bottom surfaces of the grooves. This cathode structure results in a PDP having a low discharge maintaining voltage and a high cathode current density.
