摘要:
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.

An apparatus for deflecting light of the present invention comprises: (a) at least one pair of transference electrodes arranged facing one another; (b) a drive circuit which applies a voltage among the transference electrodes; and (c) a liquid crystal which is inserted among the transference electrodes, and whose parallel stripes that function as a diffraction grating when the voltage is applied among the transference electrodes are produced at a pitch corresponding to the applied voltage. The light can be scanned if a diffracted light by the apparatus for deflecting light is converted into a scanning light and a voltage value is changed temporally to apply the voltage among the transference electrodes. In a device for reading information, the scanning light is reflected in a bar code and the reflected light is detected by an apparatus for detecting light. In a device for stereoscopic display of the present invention, the apparatus for deflecting light is used as beam deflection means for deflecting the light beamed from a picture element which organizes the pictures of the picture display means.

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.

An AC-type gas discharge display includes a base, discharge tubes which are arranged on the base in parallel to each other and which contain fluorescent phosphors, data electrodes formed on the external surfaces of the discharge tubes such that the data electrodes extend in the longitudinal direction of the discharge tubes, and display electrodes formed in pairs on the external surfaces of the discharge tubes at the opposite side of the data electrodes such that the display electrodes intersect the discharge tubes. Each of the discharge tubes has a flattened elliptical shape in cross-section thereof and includes a pair of flat portions. The data electrodes are formed on one of the flat portions and scanning electrodes and common electrodes are alternately arranged on the other one of the flat portions, and the discharge tubes are supported by the base at one or the other one of the flat portions.

A method for forming a coating film on an internal surface of an elongated tube, includes longitudinally holding the elongated tube, applying a coating solution to the internal surface of the elongated tube; and drying the coating solution while carrying out a heat process for sequentially heating the elongated tube by using a heat source. The heat process includes adjusting the descending rate of the heat source so that a through-hole in the elongated tube is clogged with the coating solution whose viscosity is reduced by heating of the heat source, and sucking the through-hole in the elongated tube from the lower side thereof so that a portion of the through-hole that is clogged with the coating solution moves downwards along the elongated tube.
