Claim 0:
1. A method for manufacturing a light emitting display device, the method comprising:
preparing a substrate having an active area in which a plurality of subpixels are disposed, and an edge area surrounding the active area;
forming a first electrode on each subpixel in the active area;
forming a first common layer on the substrate in which the first electrode is formed, the first common layer including a first covering region covering an entirety of the active area and a first surrounding region surrounding the first covering region on a portion of the edge area adjacent to the active area;
forming a conductivity improvement layer overlapping with the edge area on the first surrounding region of the first common layer;
forming a light emitting layer on each subpixel of the substrate in which the first common layer is formed;
forming a second common layer on the substrate in which the light emitting layer is formed, the second common layer including a second covering region overlapping with the entirety of the active area and a second surrounding region surrounding the second covering region on the conductivity improvement layer; and
forming a second electrode on the substrate in which the second common layer is formed, the second electrode covering the first common layer and the second common layer,
wherein the second electrode is formed to be in contact with the conductivity improvement layer in the edge area.
