Sealed structure, light-emitting device, electronic device, and lighting device

摘要

A sealed structure which has high sealing capability and whose border can be slim is provided. The sealed structure includes a pair of substrates whose respective surfaces face each other with a space therebetween, and a glass layer which is in contact with the substrates, defines a space between the substrates, and has at least one corner portion and side portions in continuity with the corner portion. The width of the corner portion of the glass layer is smaller than or equal to that of the side portion of the same. The sealed structure may comprise a highly reliable light-emitting element including a layer containing a light-emitting organic compound provided between a pair of electrodes.

1. A sealed structure comprising:
a substrate and a counter substrate respective surfaces of which face each other with a space therebetween; and a glass layer which is in contact with both of the substrate and the counter substrate, defines a sealed space between the substrate and the counter substrate, and when viewed in plan view, the glass layer comprises: a corner portion in continuity with a first side portion and a second side portion, the corner portion being continuously formed from the first side portion to the second side portion, wherein one of an inner contour and an outer contour of the first side portion is a straight line and one of an inner contour and an outer contour of the second side portion is a straight line, wherein an outer contour of the corner portion and an inner contour of the corner portion of the glass layer can each be described as a curve free of inflection points and singular points, when seen in the plan view, and wherein a width of the corner portion of the glass layer is smaller than a width of the first side portion of the glass layer, the widths being defined as distances from the inner contour to the outer contour along a direction perpendicular to the inner contour.
