Patent ID: 8778469

Claim:
An electronic device comprising: a first glass substrate having a surface including a first sealing region; a second glass substrate having a surface, the surface including a second sealing region corresponding to the first sealing region and disposed so as to face the surface of the first glass substrate; an electronic element portion disposed between the first glass substrate and the second glass substrate; and a sealing layer formed between the first sealing region of the first glass substrate and the second sealing region of the second glass substrate so as to seal the electronic element portion; wherein the sealing layer comprises a melted and solidified layer which is obtained by locally heating a sealing material, the sealing material containing sealing glass, a low-expansion filler and an electromagnetic wave absorbent, and wherein reacted layers are produced in the first and second glass substrates by reaction with the sealing layer as a result of locally heating, each of the reacted layers having a maximum depth of at least 30 nm from an interface with the sealing layer, wherein the reacted layers have central portions formed in a shape protruding toward the first and second glass substrates in comparison with portions thereof in the vicinity of end portions, wherein said central portions and said end portions are relative to a width of said reacted layers.
