Abstract (en)

In a flat type display device, first and second substrates (1,2) are disposed facing with each other, with a first electrode group (31) comprising a plurality of first electrodes (21) to serve as one of discharge electrodes, formed on the first substrate (1), and a plurality of partition walls (4) arranged parallel with a certain interval, and a second electrode group (32) comprising a plurality of second electrodes (22) to serve as the other one of the discharge electrodes, formed on the second substrate (2). Then, the second electrodes (22) are formed at least on one side surface of the partition walls (4) except the top surface, or formed in the partition walls (4) such that one side rim faces to at least one side surface of the partition walls (4) or is disposed in the vicinity of the side surface so that the plasma discharge display by the cathode glow discharge is executed. The power consumption is reduced and the brightness is enhanced. <IMAGE>
