Abstract
A method of fabricating an organic light emitting display device includes forming a first electrode in both a luminescent region and a part of a non-luminescent region, forming a buffer layer in the non-luminescent region, forming an insulation pattern on the buffer layer in the non-luminescent region, forming an auxiliary electrode on the insulation pattern in the non-luminescent region, forming an organic emission layer in both the luminescent region and the non-luminescent region, forming a second electrode in both the luminescent region and the non-luminescent region, and applying over-voltage to the auxiliary electrode, the organic emission layer on the auxiliary electrode and the second electrode.
Claims10
An organic light emitting display device, comprising:
- at least one sub-pixel driving part formed in a non-luminescent region of a bottom substrate, wherein the bottom substrate has the non-luminescent region as well as a luminescent region configured therein;
- a first electrode electrically connected to the sub-pixel driving part;
