Abstract
In a planar type plasma discharge display device including first and second electrode groups to display a desired image by plasma discharge produced between the first and second electrode groups, its accuracy may be increased, and its manufacturing may be simplified. A pair of discharge electrode groups comprising a first electrode group and a second electrode group, each formed by arraying a plurality of electrode elements, are arrayed on a common substrate in a two-dimensional fashion. Then, a desired image is displayed by plasma discharge produced between selected electrode elements of the first and second electrode groups. To solve a problem of an ordinary matrix type high-definition display device which is not reliable because an area of a terminal disposed portion is increased by the enormous number of terminals concerning the horizontal direction scanning, a terminal width is reduced or terminals are disposed very close to each other. The display device includes first and second electrode groups. The first electrode group is formed by arraying a plurality of electrode elements X extended in a first direction, and the second electrode group is formed by arraying a plurality of electrode elements Y extended in the direction crossing the first direction. The electrode element Y of the second electrode group forms adjacent four electrode elements into one set, a common terminal is led out from every other electrode elements in each set, and a plasma discharge portion is formed at a portion in which every other electrode elements X of the first electrode groups and corresponding adjacent two electrode elements in each set of the second electrode group cross to each other.
