PURPOSE: To increase both the luminance and the manufacturing efficiency of a fluorescent display tube, which is of a back-surface emission display type, by forming an anodic segment electrode of the said display tube from a mesh pattern of a conductive member.

CONSTITUTION: After a glass plate used as an insulating base plate 1 is coated with a conductive member such as Al by a sputtering method or something similar, the above conductive member is subjected to a photoetching method or something similar so as to make a feeder 4 and a mesh-like segment electrode 32. Next, only the feeder 4 is coated with an insulating layer 2. After that, the upper surface and the side surface of the electrode 32 is coated with a phosphor such as ZnOZn by an electrophoresis or something similar so as to form a phosphorous layer 33 having a pin hole. Owing to the above constitution, electrons discharged from a filament 6, after being accelerated with a grid, are made to bump against the layer 33 to make the layer 33 to emit light, and thus emitted light can be pass through the plate 1 without being reduced in its intensity. Consequently a display tube which provides an emission display with a high luminance on its back surface can be obtained.
