Publication number: 20200259109Abstract: 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).Type: ApplicationFiled: April 23, 2020Publication date: August 13, 2020Inventor: Takeru OKADA
