manufacture example 1

[0076] As the raw material oxide, the V 2 o 5 , BaO, TeO 2 , Nb 2 o 5 、Al 2 o 3 , ZnO, MnO 2 , CuO, Fe 2 o 3 , SiO 2 , CaO, P 2 o 5 The respective powders were mixed at the ratios (mol %) described in Tables 1 and 2 described below (10 g in total) and placed in a platinum crucible, heated in an electric furnace at about 1000° C. for 60 minutes to melt, and poured the melt into Put it into an alumina boat to make a glass ribbon, after cooling in the atmosphere, crush the glass ribbon with an automatic mortar, classify the crushed product, collect the crushed product with a particle size of 100 μm or less, and manufacture a powdered vanadium-based glass material No.1~22.

[0077] The glass transition point [Tg], softening point [Tf], thermal expansion coefficient, fluidity in molten state, glass gloss, laser sealing property, and color tone were examined for vanadium-based glass materials No. 1 to 22 produced by the above method. . The results are shown in Table 1 ...

manufacture example 2

[0101] The powders of vanadium-based glass materials No. 7 and No. 16 in Production Example 1 above were mixed with zirconium phosphate (maximum particle size: 5.5 μm, average particle size: about 1.0 μm) as fillers in the ratios shown in Table 3 below. , Manufactured filler-containing glass materials No.F1-F4. In addition, regarding these filler-containing glass materials No. F1 to F4, the coefficient of thermal expansion, laser sealing property, sealing strength, and color tone were examined, and the results are shown in Table 3. In addition, the measuring method and evaluation of thermal expansion coefficient, laser sealing property, and color tone are the same as that of Production Example 1. The measurement of the seal strength is as follows.

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...
