Vanadium-based glass material for local heating and sealing, flat-panel display using the glass material, and method for manufacturing the display

Abstract

A vanadium-based glass material is provided and used for sealing glass substrates in the flat-panel display by using laser heating. The low temperature processing and the laser sealing of the vanadium-based glass material are excellent. A sealing glass layer with very small thermal expansion coefficient and extremely excellent water resistance is formed, and the material cost can be greatly reduced. The vanadium-based glass material for local heating and sealing has the following glass: by mol%, 30.0%-60.0% of V2O5, 0.1-30.0% of ZnO, 10.0-25.0% of TeO2, 1.0-5.0% of Al2O3, 0.5-5.0% of Nb2O3, 0-10.0% of BaO, 0-5.0% of Fe2O3, 0-5.0% of MnO, 0-5.0% of CuO, 0-5.0% of SiO2, and 0-8.0% of CaO, substantially not including Pb or P.

Description

technical field

[0001] The present invention relates to a vanadium-based glass material and a flat plate using the glass material for sealing the junction between glass parts in an organic EL (electroluminescence) display, a liquid crystal display, etc., by local heating such as laser heating Displays and methods of manufacturing the same. Background technique

[0002] In recent years, self-luminous organic EL displays using organic light emitters such as diamines have attracted attention as flat panel displays. The organic EL display such as figure 1 As shown, it has a structure in which a parallel stripe-shaped lower electrode 2, an organic light-emitting layer 3, and an organic light-emitting layer 3 are formed on one side (inner surface) of an EL element substrate 1 made of glass in order from the lower layer side. The upper electrodes 4 in the form of parallel strips in the orthogonal direction are sealed with the sealing layer 6 between the peripheral portions betwee...
