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.
