Abstract:
A sealing material for a flat panel display contains 100 parts by weight of a compound (A) containing at least one epoxy group in the molecule, and 0.01 to 40 parts by weight of a compound (B) that generates a base upon irradiation. The compound (B) that generates a base upon irradiation is preferably a compound that generates a tertiary amine upon irradiation. The sealing material has favorable curability at low temperature, and a long pot life at room temperature, and does not cause deterioration of display members with ionic components and acids.

Abstract:
An envelope includes a face plate, a rear plate arranged so as to be opposite to the face plate, an outer frame arranged between the face and rear plates and surrounding a circumference, and a face plate joining portion for joining the outer frame and the face plate. A rear plate joining portion joins the outer frame and the rear plate to each other, with one or both of the face plate joining portion and the rear plate joining portion including a sealant having a seal function and an adhesive having an adhesive function.
Abstract:
The process for manufacturing a plasma display panel, wherein two glass substrates are sealed together using a sealing material of epoxy or polyvinyl butyrate. The sealed structure provides a space between the substrates to contain a discharge gas. The choice of an epoxy or polyvinyl butyrate sealing material allows for relatively low processing temperatures in order to cure the sealing material. This relatively low processing temperature, of between 200° C. and 300° C., lowers the risk of cracking or microcracking of intermediate layers, which are formed on the surfaces of the substrates.
Abstract:
The evacuated envelope of an image display apparatus has a rear substrate, a front substrate opposing the rear substrate, and a sidewall interposed between the rear and front substrates. A phosphor screen is formed on the inner surface of the front substrate. Electron-emitting elements are provided on the rear substrate. An indium layer is formed on a sealing surface lying between the front substrate and the sidewall. When the indium layer is heated and melted in a vacuum atmosphere, the front and rear substrates are sealed to each other, with the sidewall interposed between them.

Abstract:
An image display apparatus includes an envelope which has a front substrate and a rear substrate opposed to each other and individually having peripheral edge portions sealed together. A sealed portion is sealed by a sealing member. the sealing member has electrical conductivity and melts when supplied with current. After the sealing member in the sealed portion is supplied with current and melted during manufacture, the current supply is stopped to cool and solidify the sealing member, whereupon the respective peripheral edge portions of the front substrate and the rear substrate are selected together.
