Disclosed here is a panel structure for a large size display which utilizes the gas discharge panel called the surface discharge type panel. Among a pair of substrates arranged face to face in order to define the gas discharge space, the one substrate which is used as the electrode supporting substrate is composed of the composite substrate body where plurality of small size substrates which can be produced comparatively easily with high production yield are combined in such a form that the side edge surfaces of said substrates are aligned face to face, while the other substrate which is used as the covering substrate is composed of a large size single substrate in such a size same as said composite substrate body. Such substrate structure realizes a large size gas discharge panel having a high production yield, without requiring the large scale production facility.

Gas discharge panel

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.

Self-shift type gas discharge panel

An AC memory drive type self-shift type gas discharge panel which can prevent an accidental erroneous discharge caused by distributed abnormal charges. Abnormal charges may accumulate to a significant extent at the ends of the shift channels having write discharge cells and shift discharge cells regularly arranged. A path for leaking the abnormal charges is provided in the dielectric layer covering the electrode defining the discharge cells at the end of the shift channels.

Self shift type gas discharge panel

An AC plasma display panel with a coated thin film dielectric layer on the electrodes has a structure which includes double layers of chromium (Cr) and copper (Cu). After three metal layers of chromium, copper, and chromium are formed on a glass substrate, these three metal layers are subjected to patterning with the desired electrode pattern in such a fashion as to eliminate the upper chromium layer. Then, a thin dielectric film of alumina (Al.sub.2 O.sub.3) is evaporated onto the two remaining metal layers forming the electrodes. This combination of two layer metal electrodes and dielectric layer is very useful in providing a self-shifting plasma display panel having high quality and reliability.
