Electrode structure of an ac type plasma display panel

Abstract

An AC type plasma display panel having a first and a second electrode, each extending along a line direction and aligning along a row direction across a discharge gap therebetween, where is formed a display discharge cell. A third electrode extends along the row direction and intersects the first and second electrodes. Thus a display matrix is formed with the lines and the rows, and an address discharge cell is formed with the second electrode and the third electrode. Each of the first and second electrodes comprises a laminate of an electrically conductive transparent film stripe having a first side distant from the discharge gap and a second side near to the discharge gap with a metal film stripe thereon. A width of the metal film stripe is narrower than a width of the transparent film stripe. The metal film stripe has a third side distant from the discharge gap, and a fourth side near to the discharge gap. The metal film stripe of at least the first electrode is located such that a first distance between the second side and fourth side is smaller than a second distance between the first side and third second side, whereby a reliable long term operation can be accomplished while reducing the load of the driving circuit without decreasing the luminous efficiency.
