Abstract
A display device includes elongated display tubes each of which has a discharge gas filled and a phosphor layer formed in the tube; a flexible sheet; a plurality of electrodes; and an adhesive layer. Each of the tubes is flat elliptical in cross section and has a plane section. The flexible sheet abuts against the plane sections of the tubes to support the tubes. The plurality of electrodes are arranged on the tubes abutting surface of the flexible sheet, for applying a voltage to the tubes to generate discharges within the tubes. The adhesive layer is disposed on the tubes abutting surface of the flexible sheet to bond the flexible sheet to the plane sections of the tubes so that the electrodes of the flexible sheet face the plane sections when the flexible sheet abuts against the plane sections of the tubes.
