ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/158873
Kind Code:
A1
Abstract:
Disclosed is an electronic device capable of suppressing the occurring of cracks or breaks in glass substrates or a sealing layer when laser-sealing two glass substrates together. An electronic device (1) is provided with a first glass substrate (2), a second glass substrate (3), and a sealing layer (6) formed between these. The sealing layer (6) comprises a molten anchoring layer of a sealing material containing a sealing glass, a low expansion filler material and a laser absorption material. From a cross section view of the sealing layer (6), the sum of the perimeter lengths of the low-expansion filler material and the laser absorption material per unit surface area (the liquid inhibition value) is 0.7-1.3μm-1, and the sum of the sealing glass heat expansion coefficient multiplied by the sealing glass surface area ratio and of the low-expansion filler material heat expansion coefficient multiplied by the sum of the surface area ratios of the low-expansion filler material and the laser absorption material (the heat expansion value), is 50-90x10-7/C.
