Abstract
A sealing structure with high air-tightness and an organic electroluminescence device with high air-tightness are provided regardless of a pattern of a first metal layer overlapping with glass frit. A second metal layer is provided in a region where a common power supply line overlaps with the glass frit. Since laser light is absorbed or reflected by the second metal layer, the glass frit can be uniformly heated. Therefore, an object to be sealed can be sealed with a low-melting-point glass in which a crack is not easily generated.
