Abstract

An organic light-emitting display device includes a pixel area and a transmitting area adjacent to the pixel area. The organic light-emitting display device includes an organic light-emitting diode, a driving power wiring, and a heating pattern adjacent to the driving power wiring. The organic light-emitting diode includes a first electrode disposed in the pixel area, an organic light-emitting layer disposed on the first electrode and a second electrode disposed on the organic light-emitting layer. The driving power wiring is electrically connected to the second electrode. A portion of the organic light-emitting layer is disposed in the transmitting area. The organic light-emitting layer includes an opening area overlapping the heating pattern and at least a portion of the driving power wiring. The second electrode electrically contacts the driving power wiring through the opening area.

Claims (13)

1. A method for manufacturing an organic light-emitting display device, the method comprising:

forming a driving element on a base substrate;

forming a first electrode electrically connected to the driving element, a heating pattern spaced apart from the first electrode and a driving power wiring adjacent to the heating pattern;

forming an organic light-emitting layer covering the first electrode, the heating pattern and the driving power wiring;

heating the heating pattern to remove a portion of the organic light-emitting layer, which is adjacent to the heating pattern, to form an opening area exposing the driving power wiring; and

forming a second electrode on the organic light-emitting layer, the second electrode electrically contacting the driving power wiring through the opening area.

2. The method of claim 1 , further comprising forming a heating power wiring, wherein the heating pattern is electrically connected to the heating power wiring.

3. The method of claim 2 , wherein the heating pattern is configured to generate Joule heat by a power applied to the heating pattern through the heating power wiring.

4. The method of claim 1 , wherein the heating pattern and the driving power wiring are disposed in a same layer as the first electrode.

5. The method of claim 1 , wherein the heating pattern is formed through a different process from the first electrode, and the heating pattern includes a transparent conductive material.

6. The method of claim 1 , wherein forming the second electrode includes depositing an electrode material through a mask.

7. The method of claim 6 , wherein the heating pattern contacts the second electrode.

8. The method of claim 6 , wherein the heating pattern is spaced apart from the second electrode.
