Abstract
A plasma-addressed display device whose discharge is stabilized and which is thereby suitable for the mass production of large plasma-addressed display devices having a size in the order of meters, comprising: a first substrate having a plurality of data electrodes arranged in parallel to each other; a dielectric sheet, the first substrate and the dielectric sheet being disposed face-to-face to form a display chamber therebetween; a second substrate having a plurality of discharge electrodes, and a plurality of barrier ribs each of which is located on one of the discharge electrodes to define a discharge channel between adjacent barrier ribs, the second substrate and the dielectric sheet being disposed face-to-face to form a discharge chamber therebetween, the data electrodes and discharge channel being arranged so that they are spaced apart in the vertical and horizontal directions, respectively, each of the discharge electrodes having a width larger than the respective one barrier rib in such a manner that the pair of the discharge electrodes belonging to each of the discharge channels be exposed on the glass substrate at the bottom of the corresponding barrier for a length of 40 .mu.m or more as measured along the width direction of the discharge chamber.
