Abstract

Abstract The invention provides a light emitting device with a simple device structure capable of emitting light of various colors. The light emitting device can be produced by simple processing steps: A mold is pressed convex-and-concave against a glass substrate thereby forming a corresponding convex-and-concave structure on the glass substrate; a dielectric layer and a positive electrode layer are successively formed on the glass substrate, thereby forming a positive electrode substrate; a negative electrode substrate provided with a negative electrode layer formed thereon, is prepared; an active layer material is coated on the negative electrode substrate; and the positive and negative electrode substrates are bonded to each other via a spacer.
