Plasma display panels

摘要

A plasma display panel, of a matrix display type, has a first electrode (X) and a second electrode (Y) which constitute a main electrode pair, the first electrode and the second electrode being covered with an insulating layer (17, 18) against a discharge gas. The insulating layer comprises a magnesium oxide film (18) formed at least as a surface layer thereof which is in contact with the discharge gas, the magnesium oxide film having an impedance in the range of 230 to 330 k OMEGA /cm<2> at a frequency of 100 Hz. <IMAGE>
