Abstract
A display device is provided in which a structure of a display tube is simplified so as to achieve a cost reduction and electric connection to a driving circuit is made easy. In the display device including a group of display tubes arranged in parallel for emitting light by gas discharge, plural transparent auxiliary electrodes for display are arranged in the length direction on the outer surface of the tubular vessel that defines a discharge gas space of each of the display tubes, so that the position of a discharge portion is determined. The auxiliary electrodes at the same position in the length direction of the vessel are connected to one another electrically via a band-like power supplying conductor provided on a front substrate, and a back substrate is arranged on which a band-like conductor is provided along each of the display tubes at the back side of the group of display tubes.
