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 0.7-1.3[mu]m-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.

Description

technical field

[0001] The present invention relates to an electronic device having an electronic element portion between two glass substrates whose peripheral portions are sealed. Background technique

[0002] Organic EL display (Organic Electro-Luminescence Display: OELD), Field Emission Display (Field Emission Display: FED), Plasma Display (PDP), Liquid Crystal Display (LCD) and other flat-panel display devices (FPD) ) adopts a structure in which an element glass substrate on which a display element and the like are formed and a sealing glass substrate are arranged facing each other, and the display element is sealed with a glass package obtained by sealing the two glass substrates (see Patent Document 1). For solar cells such as dye-sensitized solar cells, studies have also been made on glass encapsulation in which solar cell elements (photoelectric conversion elements) are sealed with two glass substrates (see Patent Documents 2 to 4). .
