GLASS COMPOSITION HAVING A LOW COEFFICIENT OF THERMAL EXPANSION FOR SEALING THE OLED DISPLAY

摘要

The present invention relates to a glass composition used for encapsulating an OLED display. The glass composition can easily control coefficient of thermal expansion on a substrate having low coefficient of thermal expansion, and has excellent fluidity and high glass stability. In addition, the provided glass composition comprises: a base glass for encapsulating the OLED display; and a ceramic filter which is CaZr_4(PO_4)_6.
