Abstract:
A display device comprising:a supporting substrate; a plurality of gas discharge tubes, arranged parallel to each other on the supporting substrate, each of the gas discharge tubes having a phosphor layer formed within a tubular vessel defining a discharge space including: a supporting member independent of the tubular vessel, wherein the phosphor layer is formed on the supporting member, and the supporting member is inserted within the discharge space; wherein the supporting member has projections and the projections are also covered with the phosphor layer; and wherein the supporting member is in contact with the gas discharge tube, a plurality of signal electrodes formed in a longitudinal direction of the gas discharge tubes on a surface of the supporting substrate on which surface the gas discharge tubes are formed, the signal electrodes being in contact with outer walls of the gas discharge tubes; and a plurality of display electrode pairs formed in a direction crossing the gas discharge tubes, the display electrode pairs being in contact with front outer walls of the gas discharge tubes wherein; luminous areas are formed at areas where the signal electrodes intersect the display electrode pairs; and the projections of the supporting member partition the discharge space on a unit luminous area basis.
