ABSTRACT:
A fluorescent display device includes a substrate having a pattern display thereon, at least one pair of conductive bases, the bases being separated by a predetermined interval and facing each other in parallel on the substrate, the conductive bases each having at least one pair of position-setting holes perpendicular to the substrate; and at least one pair of supporters, each of which includes a fixing portion having at least one pair of position-setting holes corresponding to the position-setting holes of one of the bases, and a supporting portion extending from said fixing portion, one of the position-setting holes in each of the supporters being a slot. The slots correspond to a hole in a supporter so that it is unnecessary for the base specifications to be changed even in the event of variation of the intervals between the position-setting holes in the supporters.
