Gas discharge panel having plurality of shift electrodes

In a self-shifting sealed discharge panel having a gas discharge space containing an ionizable gas and a plurality of shift electrodes comprising a dielectric layer, a pair of insulating substrates spaced apart from each other for supporting said plurality of shift electrodes, said plurality of shift electrodes having edges and being coated with said dielectric layer on at least one of said pairs of insulating substrates, a plurality of bus conductors, said plurality of shift electrodes being connected regularly to said plurality of bus conductors and positioned face to face across said gas discharge space, the improvement comprising:

• each of said plurality of shift electrodes comprising a portion which is located within said gas discharge space and having a double layer structure comprising an underlayer directly formed on the respective substrate and a conductive metal layer formed on said underlayer, said dielectric layer comprising an evaporated film of insulating material covering the edge of each said double layer structure electrode so that the edge of said covered electrode has a maximum average gradient angle at 60.degree.;
• at least one of said plurality of shift electrodes further comprising a terminal portion which is located outside said gas discharge space and comprises an additional metal layer formed on said conductive layer.

In a substrate assembly for a gas discharge panel comprising a glass substrate, an electrode arrangement of electrodes having edges formed on said glass substrate, said electrode arrangement having a specified electrode pattern, the improvement comprising:

• a dielectric layer coated on said electrode arrangement, said electrode arrangement comprising a double layer structure comprising a first layer formed on said glass substrate and a second layer which is conductive and formed on said first layer, wherein said dielectric layer is uniform as a result of being evaporated on said second layer, and the edge of each said electrode of said electrode arrangement as covered by said dielectric layer having a maximum average gradient angle of 60.degree. with respect to the surface of the respective substrate on which it is formed;
• and
• said electrode arrangement further comprising a terminal portion which comprises an additional conductive layer formed on said second layer.
