Abstract: A method for manufacturing a light emitting display device, includes preparing a substrate having an active area and edge areas around the active area, forming a first electrode in each of a plurality of subpixels in the active area, forming a first common layer configured to cover an entirety of the active area and to have a first process margin in the edge areas outside the active area, forming a conductivity improvement layer on the first common layer in the edge areas, forming a light emitting layer in each of the subpixels, forming a second common layer having a large size than a size of the active area, on the light emitting layer, and forming a second electrode having a second process margin in the edge areas to cover at least the first common layer, on the second common layer.

Abstract: Disclosed are a light emitting display device and a method for manufacturing the same. The light emitting display device changes a configuration of common layers disposed in edge areas and can thus satisfy structural characteristics of a narrow bezel and prevent light leakage generated around the edge areas.
