Abstract Disclosed is a panel type display apparatus comprising a back plate and a transparent front plate, these plates facing each other at a small distance. A plurality of parallel strip-like cathodes are formed on the inner surface of the back plate facing the front plate and extend in a first direction. An insulating rib structure is formed on the inner surface of the back plate and has a lattice-like structure that extends along lines between adjacent cathodes in the aforementioned first direction and also along lines extending in a second direction at right angles to the first direction and defines a number of display element sections. A plurality of anodes are formed at least one portions of the rib structure extending in the aforementioned second direction. These anodes are formed on one side of portions of the rib structure extending in the second direction for the display element sections defined on the aforementioned one side. These anodes are isolated from the display element sections defined on the other side of the rib structure portions mentioned by partitioning rib portions raised therefrom and in contact with the front plate. Seed discharge sections are each defined in each of the display element sections in a portion of the cathode surface thereof in the vicinity of the corresponding anode.
A panel type display apparatus comprising: a transparent front plate; a back plate facing said front plate at a small distance; said front plate sealed to the back plate and containing a discharge gas therein; a plurality of parallel strip-like cathodes formed on the inner surface of said back plate facing said front plate and extending in a first direction; an insulating rib structure formed on the inner surface of said back plate and having a lattice-like structure extending along lines between adjacent cathodes in said first direction and also along lines extending in a second direction at right angles to said first direction; a plurality of partitioning ribs raised from at least portions of said insulating rib structure extending in said second direction and in contact with said front plate; a plurality of anodes formed to extend along one side of said partitioning ribs; and seed discharge sections each defined in a portion of the cathode surface in each said display element section in the vicinity of the corresponding anode.
