LIGHT EMITTING ELEMENT

摘要

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).

1. A light emitting element, comprising:
a flexible portion including a glass substrate, and an organic functional layer which includes a light emitting layer, and is on one surface side of the glass substrate, wherein, when the flexible portion is curved in a curving direction such that one surface of the flexible portion is a concave surface, and the other surface of the flexible portion is a convex surface, a first surface is positioned on the concave surface side among of surfaces of the glass substrate, and when a thickness of the glass substrate is T, a compressive stress is applied to a portion of the glass substrate having a distance from the first surface of the glass substrate that is less than or equal to L (L>T/2) when the flexible portion is curved.
