Abstract

A light emitting element includes a flexible plate-like portion having a glass substrate, and an organic functional layer formed on one surface side of the glass substrate. The organic functional layer includes a light emitting layer. When the plate-like portion is curved in a prescribed curving direction, and one surface of the plate-like portion is a concave surface, and the other surface thereof is a convex surface, a surface which is positioned on the concave surface side among both surfaces of the glass substrate is referred to as a first surface. When the plate-like portion is curved in a curving direction, and the one surface of the plate-like portion is a concave surface, and the other surface thereof is a convex surface, a compressive stress is applied to a portion whose distance from the first surface of the glass substrate is less than or equal to L (L>T/2).

Claims (14)

1. A light emitting element comprising:

a glass substrate;

an organic functional layer comprising a light emitting layer, the organic functional layer being formed on one surface side of the glass substrate; and

a resin layer having a thickness greater than that of the glass substrate,

wherein the light emitting element is fixed along a curved surface of a fixation member, and is curved such that one surface side of the light emitting element at which the resin layer is formed relative to the glass substrate is a convex surface,

wherein a center of a thickness direction of the glass substrate is closer to a concave surface of the light emitting element than a center of a thickness direction of the light emitting element is,

wherein the glass substrate comprises the one surface and another surface opposite to the one surface,

wherein the resin layer is positioned on the another surface side.

2. The light emitting element according to claim 1 ,

wherein the center of the thickness direction of the light emitting element is positioned in the resin layer.

3. The light emitting element according to claim 1 ,

wherein the center of the thickness direction of the light emitting element is positioned in the glass substrate.

4. The light emitting element according to claim 1 ,

wherein light of the light emitting layer is emitted opposite to the glass substrate and the resin layer.
