A full color three electrode surface discharge type plasma display device that has fine image elements and is large and has a bright display. The three primary color luminescent areas are arranged in the extending direction of the display electrode pairs in a successive manner and an image element is composed by the three unit luminescent areas defined by these three luminescent areas and address electrodes intersecting these three luminescent areas. Further, phosphors are coated not only on a substrate but also on the side walls of the barriers and on address electrodes. The manufacturing processes and operation methods of the above constructions are also disclosed.

Full color surface discharge type plasma display device

A plasma display panel has a good productivity of partition formation and air exhaustion process and realizes a bright and stable display. A discharge gas is filled in a gap between two substrates. A mesh-patterned partition is arranged on the inner surface of one of the substrates for dividing the gap into plural squares corresponding to a cell arrangement. The partition has low portions forming a mesh-like air path that travels through all of the gas-filled space enclosed by the partition, in a plan view.A plasma display panel includes two spaced substrates defining a gap therebetween. The gap is divided by intersecting walls into columns and rows of discharge cells. Portions of a wall that are lower in height than remaining portions of the wall define a flow path. The plasma display panel realizes a bright and stable display.

Plasma display panel and method for manufacturing the same

Tubulation tubing of a display panel includes a flange at one end and a ring-shape adhesive member placed on a display panel to align a vent hole of the display with an opening of the tubulation tubing and the flange of the tubulation tubing is bonded to the display panel via the adhesive member.

In accordance with the present invention, there is provided a method of manufacturing a plasma display panel of the type which includes a discharge space defined between a pair of substrates and sealed by a sealant, the method comprising a first step of forming the sealant on at least one of the substrates and stacking one substrate on the other through the intermediation of the sealant, a second step of reducing the pressure in the space existing between the pair of substrates due to the presence of the sealant and melting the sealant by heating, a third step of curing the sealant to thereby firmly attach the pair of substrates to each other and define a predetermined discharge space, a fourth step of removing impurities in the discharge space, and a fifth step of filling the discharge space with discharge gas.

A method of bonding a tubulation tubing of a display panel includes the steps of preparing a tubulation tubing having a flange at one end and a ring-shape adhesive member, placing the tubulation tubing and the adhesive member on a display panel to align the vent hole with an opening of the tubulation tubing, holding the tubulation tubing by pressing the flange of the tubulation tubing to a face of the display panel with a pressing tool, and heating to soften the adhesive, thereby bonding the flange of the tubulation tubing to the display panel via the adhesive member.

Method of bonding tubulation tubing of display panel

A plasma display panel has front and back substrates, each in a warped state in which a central portion of the substrate projects forwardly relatively to a peripheral portion thereof, presenting a convex front surface, a stress produced in the front and rear substrates pressing the front and rear substrates together with an elastic deformation. A height difference ratio of a central portion, measured from a central part of a short side, of each substrate, divided by a longitudinal width of the substrate is preferably less than 0.1% for each of the substrates.
