Abstract
The invention provides a glass member provided with a sealing material layer, which suppresses generation of failures such as cracks or breakage of glass substrates or a sealing layer even when the distance between two glass substrates is narrowed, and thereby makes it possible to improve the sealing property between the glass substrates and its reliability. A glass substrate has a surface provided with a sealing region, on which a sealing material layer having a thickness of at most 15 μm is formed. The sealing material layer includes a fired material of a glass material for sealing containing a sealing glass, a laser absorbent and optionally a low-expansion filler, wherein the total content of the laser absorbent and the low-expansion filler being the optional component in the glass material for sealing is within the range of from 2 to 44 vol %.
