1. A light emitting apparatus having at least one light emitting element over an insulator, the light emitting element comprising;
- an anode having a first end portion and a second end portion formed over said insulator, the anode extending in a first direction wherein each of the first end portion and the second end portion of the anode extends along said first direction;
a first wiring and a second wiring, wherein the first wiring is formed over and in contact with the first end portion of the anode, the second wiring is formed over and in contact with the second end portion of the anode, the first wiring and the second wiring extend in the first direction, and the first wiring and the second wiring are not part of the anode;
an insulating film covering both edge portions of the anode along the first direction, the first wiring, and the second wiring, wherein the insulating film has a planarized surface over the both edge portions of the anode, the first wiring and the second wiring;
an electroluminescent layer formed over the insulating film and the anode, wherein the electroluminescent layer is in direct contact with a part of the anode; and
a cathode formed over the electroluminescent layer.

Abstract
A light emitting apparatus with high homogeneity in image quality is provided, which includes anodes 102 on an insulator 101, cathodes 107 orthogonal to the anodes 102, and EL layers 106 interposed between the anodes 102 and the cathodes 107, and auxiliary wirings 103 are electrically connected to the anodes 102. The auxiliary wirings 103 are made of a material lower in resistance than that of the anodes 102, thereby being capable of reducing the wiring resistance of the anodes 102.
