Glass pattern and method for forming the same, sealed body and method for manufacturing the same, and light-emitting device

摘要

A glass pattern that can be used for a substrate provided with a material having low heat resistance and has increased productivity is provided. Further, a sealed body having high hermeticity and increased productivity is provided. Furthermore, a light-emitting device with high reliability including such a sealed body is provided. A glass sheet is used for a main portion of a glass pattern such as a straight line portion and a curved portion. In a joint portion of two glass sheets arranged in the corner portion, the straight line portion, or the like of the glass pattern, a frit paste is provided in contact with the glass sheets and is locally heated to remove the binder from the frit paste and to form a glass layer; thus, the glass sheets are fused to each other without any space provided therebetween.

主权项

1. A method for manufacturing a sealed body, comprising the steps of:
providing a first glass sheet and a second glass sheet over a first substrate so that the first glass sheet and the second glass sheet do not overlap with each other; applying a frit paste including a glass frit and a binder so that a layer of the frit paste is in contact with a first side surface of the first glass sheet and a side surface of the second glass sheet; forming a glass layer by heating the layer of the frit paste to remove the binder from the layer of the frit paste; bonding a second substrate and the first substrate in a position in which the second substrate is in contact with a top surface of the first glass sheet, a top surface of the second glass sheet, and a top surface of the glass layer such that the second substrate does not overlap a part of the top surface of the first glass sheet; and irradiating in the position the first glass sheet, the second glass sheet, and the glass layer with laser light, wherein irradiating the first glass sheet with the laser light is conducted by oblique irradiation such that a second side surface of the first glass sheet and the part of the top surface of the first glass sheet are irradiated with the laser light.
