The first object of the present invention is to provide a PDP with improved panel brightness which is achieved by improving the efficiency in conversion from discharge energy to visible rays. The second object of the present invention is to provide a PDP with improved panel life which is achieved by improving the protecting layer protecting the dielectrics glass layer. To achieve the first object, the present invention sets the amount of xenon in the discharge gas to the range of 10% by volume to less than 100% by volume, and sets the charging pressure for the discharge gas to the range of 500 to 760 Torr which is higher than conventional charging pressures. With such construction, the panel brightness increases. Also, to achieve the second object, the present invention has, on the surface of the dielectric glass layer, a protecting layer consisting of an alkaline earth oxide with (100)-face or (110)-face orientation. The protecting layer, which may be formed by using thermal Chemical Vapor Deposition (CVD) method, plasma enhanced CVD method, or a vapor deposition method with irradiation of ion or electron beam, will have a high sputtering resistance and effectively protect the dielectrics glass layer. Such a protecting layer contributes to the improvement of the panel life.

The present invention intends to provide a gap-forming sheet for laminating a plurality of flat plate electrodes, for example, for controlling electron beam at high accuracy in a short period of time. Gap-forming sheets each including a support member formed by depolymerizing resin, gap members for providing gaps between the flat plate electrodes, and a bonding paste for bonding the flat plate electrodes, are held between the flat plate electrodes, which are baked to decompose the support members, and thus, by melting the bonding paste, the flat plate electrodes are joined together for lamination, with gaps being provided by the gap members.

Method of joining flat electrodes

This invention proposes methods of effectively forming a metal-backed layer and an anode using a metal film transferring sheet in which micro-holes are formed. that is, the metal film transferring sheet is structured by forming a metal film on a mold-releasable, highly characteristic sheet. Then, the metal film having micro-holes of the metal film transferring sheet is transferred onto a phosphor screen. Or, on the metal film of the above-mentioned metal film transferring sheet, is formed a phosphor screen and the metal film, the phosphor screen, etc. are all transferred onto a face plate form an anode of a cathode-ray tube. Then the methods proposed by this invention are applied for making phosphor products of, for example, a cathode-ray tube or a plasma display. According to these methods, there is no need to use a large-scaled manufacturing facility and high quality, low cost products can be obtainable.

A method of forming an ink image with a thermo-sensitive ink by using a printing plate that is used in dry lithographic printing, and printing the ink image onto an object. An ink remover is placed via a thermo-sensitive ink layer that is in a heated state on a printing surface of a printing plate having a part receptive to ink and a part capable of repelling ink. The printing plate and the ink remover are separated after they are cooled so that the ink layer on the part capable of repelling ink is transferred to the ink remover. The ink image obtained on the printing plate or the ink remover is transferred to an object. Printing that does not require maintenance that has been essential to conventional dry lithographic printing becomes possible.
