GLASS SUBSTRATE WITH SEALING MATERIAL LAYER AND GLASS PACKAGE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a glass substrate with a sealing material layer capable of improving accuracy of laser sealing even when the thermal expansion coefficient of the glass substrate is high.SOLUTION: A glass substrate with a sealing material layer includes a sealing material layer on the glass substrate. The thermal expansion coefficient of the glass substrate is ≥70×10/°C in the temperature range of 30 to 380°C. The sealing material layer is the sintered body of a sealing material. The sealing material contains 55 to 95 volume% of bismuth-based glass and 5 to 45 volume% of a refractory filler, and is used for laser sealing.
