Abstract: A full color three electrode surface discharge type plasma display device that has fine image elements and is large and has a bright display. The three primary color luminescent areas are arranged in the extending direction of the display electrode pairs in a successive manner and an image element is composed by the three unit luminescent areas defined by these three luminescent areas and address electrodes intersecting these three luminescent areas. Further, phosphors are coated not only on a substrate but also on the side walls of the barriers and on address electrodes. The manufacturing processes and operation methods of the above constructions are also disclosed.

Abstract: An EL device having an electrode arrangement including first electrodes and at least one row of second electrodes intersecting the first electrodes and energized by a combination of the first and second electrodes. The second electrodes are divided into a plurality of sub-electrode portions. The electrode arrangement is such that the first electrodes each comprise a plurality of segments that are commonly-connected and intersect different sub-electrode portions. Another electrode arrangement is such that the first electrodes are arranged in a belt form and intersect different sub-electrodes portions in a meander manner.The EL device can be applied to an electrophotographic printing system as an optical system for forming a latent image. EL elements are repeatedly energized with the same data to give a sufficient intensity of light on a light sensitive medium, and deenergized for a time in which the intensity is decreased to a low level.

Abstract: An AC memory driving type self-shift type gas discharge panel prevents accidental abnormal discharges caused by deviated abnormal charges. Abnormal charges are significantly accumulated at both ends of a shift channel consisting of a regular arrangement of a write discharge cell and shift discharge cells. Therefore, conductive layers are provided adjacent to at least both ends of the shift channel in order to dissipate the abormal charges.
