Abstract: PROBLEM TO BE SOLVED: To provide a gas discharge display panel, in which the maintaining period, which contributes the display emission, among the operating period of a gas discharge display panel is large, by setting the number of arrangement of scanning electrodes and maintaining electrodes, which are arranged opposite to writing electrodes through a discharge space, at the specified number or less. SOLUTION: A discharge space 7 is formed between a glass plate 2 and a glass plate 11, and plural scanning electrodes 3 are provided on the surface of the glass plate 2 in the glass plate 11 side in practically parallel with each other, and plural maintaining electrodes 4 are arranged in parallel with each other between the scanning electrodes 3 so as to be inserted each other and so as to form each pair with the scanning electrode 3. Plural writing electrodes 10 are provided on the surface of the glass plate 11 in the glass plate 2 side so as to be opposite to the scanning electrodes 3 and the maintaining electrodes 4 through the discharge space 7. With this structure, the number of each arrangement of the scanning electrode 3 and the maintaining electrode 4 is set at the specified number or less. A gas discharge display panel, in which the share of the maintaining period, which contributes for the display emission, among the operating period of the discharge type display panel is large, is thereby obtained.

Abstract: PURPOSE:To provide a luminescent panel capable of arranging a picture element region in high density, with less uneven brightness, and no complex outside wiring, and provide its driving device and a color image display. CONSTITUTION:A luminescent panel has a plurality of through-holes 12a for exposing part of each filament 8 in an insulating plate 11 covering a plurality of filaments 8 arranged on a back base board 7, and each through-hole 12a forms one unit of a picture element region together with fluorescent material layers 13a-13c formed in the adjacency of the through-holes 12a. The fluorescent material layers 13a-13c of each picture element region are housed in a cavity 15a of a separating wall 14 formed on the insulating plate 11 and separated from an adjacent fluorescent material layer. The cavity 15a forms a discharge space by using a translucent front plate 16 installed on the separating wall 14 as a cover, each discharge space communicates with the through-hole 12a at its one end in the lengthy direction and faces an anode 17 formed on the lower surface of the front plate 16 at its other end.
