A light emitting element includes a flexible plate-like portion, and a fixation member fixing the flexible plate-like portion. The flexible plate-like portion includes a light extraction film, a sealing layer, an organic functional layer including a light emitting layer, a glass substrate, and a resin layer having a thickness greater than that of the glass substrate. The fixation member fixes the flexible plate-like portion such that the flexible plate-like portion includes a concave surface and a convex surface opposite to the concave surface, and such that the glass substrate is positioned on a side of the concave surface relative to the resin layer. A center of a thickness direction of the glass substrate is closer to the concave surface than a center of a thickness direction of the flexible plate-like portion is.
