ABSTRACT:
According to the present invention, in a plasma display discharge tube in which a plurality of stripe-like anode electrodes (11) and a plurality of stripe-like cathode electrodes (9) are arranged at a predetermined interval to be crossed each other, to thereby constitute an X-Y matrix electrode with a space at each of the crossing portions thereof as a pixel and a plurality of pixels are selectively excited according to an image to display an image, there is provided a plasma display discharge tube in which there are provided an AC type memory electrode (1) arranged opposite to the X-Y matrix electrode (9) and (11) common to all the pixels, and an AC type auxiliary electrode (5) in contact with the AC type memory electrode (1) through an insulating layer and supplying an electric power through a coupling capacitor formed between the same and the AC type memory electrode (1), wherein a memory discharge display is performed between the X-Y matrix electrode (9) and (11) and the AC type memory electrode (1). According to the present invention with the above arrangement, the electrode structure can be simplified to reduce manufacturing steps in number, driving using a pulse memory scheme which can be conventionally realized by only a DC type plasma display discharge tube having high emission efficiency and excellent responsibility is made possible, and a plasma display discharge tube having a long-life AC type electrode can be obtained.
