GLASS MEMBER WITH SEALING MATERIAL LAYER, ELECTRONIC DEVICE USING SAME AND METHOD FOR PRODUCING SAME

摘要

Provided is a glass member with a sealing material layer which is capable of suppressing generation of flaws such as cracks, fissures, etc. in a glass substrate or a sealing layer when narrowing the space between two glass substrates, and improving the sealing properties between the glass substrates and the reliability thereof. A glass substrate (3) comprises a surface (3a) which is provided with a sealing area. A sealing material layer (9) having a thickness of less than 7 µm is formed on the sealing area of the glass substrate (3). The sealing material layer (9) comprises a sealing glass and an inorganic filling material containing a laser absorbing material, and is composed of a calcined layer of a glass material for sealing in which the content of the inorganic filling material is 2-44 volume%. The surface area of the inorganic filling material in the glass material for sealing is in the range of over 6 m2/cm3 and less than 14 m2/cm3. The difference between a coefficient of thermal expansion a1 of the sealing material layer (9) and a coefficient of thermal expansion a2 of the glass substrate (3) is within the range of 15-70 (x 10-7/C°).
