摘要： PROBLEM TO BE SOLVED: To prevent generation of breaks even when a dielectric layer is formed thin in a PDP, and furthermore prevent the generation of the crack or the like on the glass substrate in a manufacturing process of the PDP even though the glass substrate is made thinner than before.
SOLUTION: In the PDP, when the dielectric layer is coated on a silver electrode of the surface of a panel, the surface of the silver electrode is coated by a layer 13a composed of 'a metal oxide to form hydroxyl groups on the surface' by a CVD method, and the dielectric layer 13 is coated on it, or the dielectric layer is formed by the metal oxide by using a vacuum process such as the CVD method. Furthermore, if the dielectric layer is formed by the vacuum process method or flame spray coating, buckling or the crack of the panel caused by the baking of the dielectric layer is eliminated. Furthermore, if borosilicate glass in which alkaline component of 6.5 wt.% or less is used as the material of glass substrates 11, 21, this is more effective.

摘要： PROBLEM TO BE SOLVED: To provide a plasma display panel enabling improvement of discharge generation response, when a drive voltage is applied, proper image displaying and long product life. SOLUTION: The plasma display panel comprises the first substrate where a plurality of electrode pairs, consisting of the first electrode and the second electrode respectively are disposed in parallel in stripe formation and are covered with a dielectric layer further, and the second substrate where the third electrodes are disposed in stripe formation, where both the substrates are facing each other via partitioning ribs. The dielectric layer is covered with XA, where X is at least one chosen from Al, B or Ga and A is at least one chosen from O, N, Ar, H, He, Ne, Kr or Xe, and the XA consists of at least two elements. Thereby, a protective layer is formed on a surface layer of the dielectric layer, in order to obtain high electron emitting ability of the protective layer, sputtering proof of the protection layer and little influence due to impurity gases on the protective layer.

摘要： PROBLEM TO BE SOLVED: To make continuous monitor possible with high accuracy even in an atmosphere where the range of an applicable film forming rate is wide and a large quantity of light of the same wavelength as the characteristic wavelength of splashing particles is generated like sputtering. SOLUTION: The luminous flux 9 emitted from a light source 1 including the characteristic wavelength of the splashed particles of a film forming device 6 is intermitted at a prescribed period by a chopping means 18 and is then split by a beam splitting means 17 to a search luminous flux 14 and a reference luminous flux 15. The search luminous flux 14 passes a particle splashing region 13 and enters a photodetector 3a through an optical filter 2a from which a search light intensity signal 23 is outputted. A reference light intensity signal 22 is similarly obtd. from the reference luminous flux as well. A data processing means 20 executes phase detection and level detection of both light intensity signals, thereby estimating the absorbance by the splashed particles, i.e., the film forming rate. The processing means estimates the thickness of the formed film by time-integrating this rate.

摘要： PURPOSE: To provide a large-area, long-life electron emitting cathode and electron emitting element at a low lost with good producibility by impressing a voltage between a counter-anode and an n-type semiconductor film where part of granular diamond protrudes at the surface, and thereby allowing electrons to be emitted. CONSTITUTION: An electron emitting element 10 is structured, for example, so that an electron emitting cathode 14 is formed on a base board 12. Electroconductive diamond grains of p-type having particle sizes from several nm to several μm are mixed with carbon fine powder, and thereto an appropriate solvent is added so that a paste is prepared. By means a printing process a film is formed on the board 12 to such a thickness that part of the diamond protrudes at the surface certainly, and the obtained film is subjected to a baking process. An insulative film 16 of silicon oxide etc., and a gate electrode 18 of conductive metal such as aluminum are formed on the cathode 14, and an opening 20 penetrating the film 16 and electrode 18 is provided for exposing the cathode 14. Finally the anode 22 is confronted to the cathode 14, and the two are put in a vacuum and sealed, and thus an intended element 10 is completed.
