Abstract
The present invention provides an organic light emitting display (OLED). The OLED includes a substrate, a first electrode arranged on a subpixel area of the substrate, an organic light emitting layer arranged on the first electrode, and a second electrode arranged on the organic light emitting layer, which extends to a non-subpixel area. An auxiliary electrode that is connected to the second electrode is arranged on the substrate, thereby the auxiliary electrode applies a same voltage as that of the second electrode.
