Abstract:
1. A light emitting device comprising: a thin film transistor; a first electrode connected to one of a source of the thin film transistor and a drain of the thin film transistor, an insulating material covering an end portion of the first electrode, a second electrode covering a side face of the insulating material and contacting with the first electrode, a light emitting layer comprising an organic material on the second electrode and a first portion of the insulating material, a third electrode in contact with the light emitting layer comprising the organic material and a second portion of the insulating material, an auxiliary electrode in contact with the third electrode and becoming the same electric potential as the third electrode, wherein the auxiliary electrode comprises the same material as the second electrode, and wherein the second electrode is fanned in a concave shape partially having a curved surface, and reflects a light emitted from the light emitting layer comprising the organic material.
