PROCESS FOR PRODUCING GLASS MEMBER PROVIDED WITH SEALING MATERIAL LAYER AND PROCESS FOR PRODUCING ELECTRONIC DEVICE
First Claim
1. A process for producing a glass member provided with a sealing material layer, which comprises a step of preparing a glass substrate having a sealing region;
- a step of applying a first paste for a sealing material which contains a first glass material for sealing containing no laser absorbent and a second paste for a sealing material which contains a second glass material for sealing containing a laser absorbent, in this order on the sealing region of the glass substrate; and
a step of firing a laminate film of a coating layer of the first paste for a sealing material and a coating layer of the second paste for a sealing material, to form a sealing material layer having a laminated structure of a layer of the first glass material for sealing and a layer of the second glass material for sealing on the sealing region.

Abstract
Laser sealing property and reliability of a glass panel are increased by suppressing cracks, fractures, separation and the like of glass substrates and a sealing material layer at the time of laser sealing.
A first paste for a sealing material containing no laser absorbent and a second paste for a sealing material containing a laser absorbent are applied in this order on a sealing region 2a of a glass substrate 2. A laminate film of a coating layer 11 of the first paste for a sealing material and a coating layer 12 of the second paste for a sealing material is fired, to form a sealing material layer 3 having a laminated structure of a layer 4 of the first glass material for sealing and a layer 5 of the second glass material for sealing. The second glass substrate 2 having such a sealing material layer 3 is laminated with a glass substrate having an element-formed region, and the sealing material layer 3 is irradiated with a laser light from the side of the layer 4 of the first glass material for sealing through the second glass substrate 2 for bonding.
