ABSTRACT:
A high efficiency plasma display panel (PDP) has a discharge cell structure in which front discharge electrodes and rear discharge electrodes are optimally positioned to maximize discharge efficiency and greatly increase light transmittance. The PDP includes: a transparent front substrate; a rear substrate arranged in parallel with the front substrate; front barrier ribs made of a dielectric material and located between the front substrate and the rear substrate so as to define discharge cells together with the front substrate and the rear substrate; front discharge electrodes located in the front barrier ribs such that they surround the discharge cells and are separated from the front substrate; rear discharge electrodes located in the front barrier ribs such that they surround the discharge cells and are separated from the front discharge electrodes; rear barrier ribs located between the front barrier ribs and the rear substrate so as to define the discharge cells together with the front barrier ribs, the front substrate and the rear substrate; fluorescent layers located in spaces defined by the rear barrier ribs and the rear substrate; and a discharge gas deposited in the discharge cells.
