Abstract: PURPOSE:To accomplish a plasma display device which gives stable main discharging and high brightness, high contrast characteristics. CONSTITUTION:A priming electrode 5, dielectric substance layer 6, fluorescent substance film 14 are furnished on the inner surface of a back plate 4, while a clear stripe-form anode 12, insulative diaphragm 15, and cathode 16 are provided on the inside surface of a facade plate 1. The insulative diaphragm is made in matrix form and is provided with a number of No.1 parallel line regions 15a, stretching in one direction, and a number of No.2 parallel line regions 15b extending as intersecting these parallel line regions 15a. The cathode 16 is made in the form of ladder, whose longer edges are located in two adjoining No.2 parallel line regions 15b while shorter edges positioned in the No.1 parallel line regions 15a. Thereby the current density of the cathode is enhanced, and a high brightness is obtained owing to the see-through type, and also a good contrast is presented because of viewing through ladder-form cathode. Thus a severance of cathode does not directly cause futal damage.
