GLASS FRIT USING GLASS POWDER WITH LOW MELTING POINT AND CRYSTALLINE CERAMIC FILLER WITH LOW EXPANSION AND PASTE COMPRISING THE SAME

摘要

Disclosed are a glass frit using low melting point glass powder with superior durability, sealing reliability, and water resistance which is suitable for an OLED panel sealing, and a low expansion crystalline ceramic filler which controls a coefficient of thermal expansion, and a paste including the same. According to the present invention, the low melting point glass frit comprises the low melting point glass powder consisting of 0.1-20mol% of V2O5, 30-60mol% of ZnO, 10-30mol% of B2O3, 0.1-10mol% of BaO, 0.1-10mol% of SiO2, 0.1-15mol% of TeO2, and 2-20mol% of at least one of CuO, Fe2O3, and Co3O4; and less than 70 parts by weight of low expansion crystalline ceramic filler with respect to 100 parts by weight of the low melting point glass powder.
