Light emitting device and electronic device

摘要

To improve light extraction efficiency of light emitting elements such as electroluminescent elements. A first electrode 101, a light emitting layer 102, and a second electrode 103 are formed over a substrate 100, which partially constitute a light emitting element. Light produced in the light emitting layer 102 is emitted out through the second electrode 103. A plurality of three-dimensional bodies 104 are provided in contact with a surface of the second electrode 103. With the provision of the bodies 104, light totally reflected between the second electrode 103 and the air enters the bodies 104 and can be emitted through faces of the bodies 104 that are not parallel to the interface between the bodies and the second electrode 103.

主权项

1. A method for manufacturing a light-emitting device, the method comprising:
forming a first electrode; forming a light-emitting layer over the first electrode; forming a second electrode over the light-emitting layer; forming a resin layer over the second electrode so as to allow the resin layer to be in direct contact with the second electrode; bringing a stamper having a convex-concave surface into contact with the resin layer so that a surface shape of the stamper is transferred to the resin layer; wherein the convex-concave surface is covered by titanium oxide; curing the resin layer; irradiating the stamper with light after the resin layer is cured while maintaining the direct contact with the stamper and the cured resin layer such that the adhesion of the titanium oxide to the resin layer is decreased; and separating the stamper from the resin layer.
