Abstract: A seal plate is installed for sealing tightly an exhaust hole provided to a glass substrate of the back side of a PDP (flat display panel). The air is directly exhausted from internal spaces via the exhaust hole and gas is sealed into an enclosure. The seal plate is heat-secured to the exhaust hole so as to seal the internal spaces tightly.

Abstract: The steps of forming a panel includes a first step of forming a pattern-forming material layer having a predetermined pattern (bus-electrode material layer and BS material layer) on a substrate through an injection coating method such as an ink-jet method and a dispenser method, a second step of forming a dielectric-layer forming material layer in such a manner as to cover the pattern-forming material layer formed at the first step; and a third step of simultaneously calcining the pattern-forming material layer and the dielectric-layer forming material layer.

Abstract: A plasma display panel includes a first additional dielectric layer 11A protruding from a backside of a dielectric layer 11 toward the inside of a discharge space S and extending along an edge of a discharge cell C extending in parallel to the row direction; and a second additional dielectric layer 11B formed to protrude from a portion of the backside of the dielectric layer 11 opposing a vertical wall 15a of a partition wall 15 toward the inside of the discharge space S, and to extend in the column direction to shield the adjacent discharge cells C in the row direction from each other in cooperation with the vertical wall 15a.

Abstract: A plasma display panel such that a sealing layer 10 is used for sealing the peripheral edge portions of a pair of glass substrates 1 and 3 and that first partition walls 6 for respectively providing discharge spaces 7 in a display area 9 between the glass substrates 1 and 3. A second partition wall 11 is so disposed as to surround the display area 9 inside the sealing layer 10 and is brought into intimate contact with the pair of glass substrates 1 and 3.

Abstract: A plasma display panel in which the reliability of seal bonding of a chip tube is assured and an evacuation working efficiency is improved. In a plasma display panel with a structure in which a glass substrate on the display surface side and a glass substrate on the rear side are adhered so as to be hermetically bonded by sealing layers through partitions and a gas is introduced into the space between the two glass substrates, an evacuation and gas charging hole is formed in one of the glass substrates and crystalline glass powder of a low melting point is molded into a predetermined shape and is baked, thereby seal bonding the chip tube into the evacuation and gas introducing hole.

Abstract: A plasma display panel comprises: a front glass base-plate provided on the front side of the plasma display panel; a rear glass base-plate provided on the rear side of the plasma display panel; a plurality of row electrode pairs provided on an internal surface of the front glass base-plate; a dielectric layer covering the row electrode pairs; a plurality of column electrodes provided on an internal surface of the rear glass base-plate. At least one electrode of each row electrode pair has a main body portion extending in a horizontal direction, and has a protruding portion in a unit luminous area. Further, each protruding portion consists of a transparent electrically conductive film and is formed into an isolated island in a unit luminous area.

Abstract: The object of the present invention is to provide a an optical recording medium provided with a reflective film having a high reflectivity and durability and a means for producing thereof, and it can be obtained by a method comprising the steps of: first placing on a heating object an aluminum metal alloy containing at least one of 0.05-0.2 wt.% metal selected from the group of iron, copper and silicon, and also having 0.7-3.0 wt.% manganese; and evaporating the aluminum metal alloy in a vacuum by means of a vapor deposition process to an information signal recorded surface of a transparent synthetic resin plate. In other words, an optical recording medium according to the present invention is provided with a light reflective film covering an information signal recorded surface of a transparent synthetic resin plate, wherein the light reflective film is formed in a vacuum by means of a vapor deposition process of an aluminum metal alloy containing at least one of 0.05-0.2 wt.

Abstract: An optical disk is provided with a protective layer which is an adhesive which is non-tacky at room temperature in the case of a one sided disk; and which is useful as a tacky adhesive at room temperature in the case of a two sided disk made from two one-sided disks bonded to one another.
