示管。 A phosphor is provided on a substrate glass, a wiring layer provided on the substrate glass, an insulating layer covering the wiring layer, and a plurality of conductor pieces connected to the wiring layer through through holes provided in the insulating layer. In the fluorescent display tube, the insulating layer, excluding the anode, has at least a portion of the insulating layer covered with the phosphor. A fluorescent display tube characterized in that the grid is formed higher than the surface of the layer and is supported by the insulating layer.
