Abstract:
1. A light-emitting device comprising: a substrate; a first electrode and a second electrode each over the substrate, wherein the first electrode and the second electrode are arranged parallel to each other; an insulating bank over the first electrode and the second electrode, wherein the insulating bank comprises a first opening overlapping the first electrode and a second opening overlapping the second electrode; a first organic thin film over the first electrode, the second electrode, and the insulating bank, wherein the first organic thin film is in contact with the first electrode in the first opening and in contact with the second electrode in the second opening; a second organic thin film over the first electrode with the first organic thin film interposed therebetween; a third organic thin film over the second electrode with the first organic thin film interposed therebetween; and a third electrode over the second organic thin film, the third organic thin film, and the insulating bank, wherein the first organic thin film comprises: wherein a thickness of the third region of the first organic thin film is larger than a thickness of the first region of the first organic thin film and a thickness of the second region of the first organic thin film.
