Organic light-emitting display apparatus and method of manufacturing the same
A method of manufacturing an organic light-emitting display apparatus including forming a liftoff layer containing a fluoropolymer on a substrate, forming a photoresist on the liftoff layer and patterning the photoresist by removing a portion thereof, etching, using a first solvent, the liftoff layer in a region where the photoresist is removed so that a portion of the liftoff layer remains on the substrate, forming an etch stop layer above the liftoff layer that remains on the substrate and above a region where the photoresist remains on the liftoff layer, and removing, using a second solvent, the liftoff layer under the region where the photoresist remains on the liftoff layer.
1. An organic light-emitting display apparatus, comprising:
a first first electrode disposed on a substrate;
a second first electrode disposed separate from the first first electrode;
a pixel defining layer covering an edge of the first first electrode and the second first electrode;
a layer disposed on the pixel defining layer, the layer comprising a fluoropolymer and contacting a top surface of each of the first first electrode and the second first electrode;
a first organic functional layer comprising a first light emitting layer, the first organic functional layer having a lower surface contacting the top surface of the first first electrode;
a second organic functional layer comprising a second light emitting layer, the second organic functional layer having a lower surface contacting the top surface of the second first electrode; and
a second electrode commonly disposed on the first organic functional layer and second organic functional layer.
2. The organic light-emitting display apparatus of claim 1 , wherein a first color of light emitted from the first light emitting layer is different from a second color of light emitted from the second light emitting layer.
3. The organic light-emitting display apparatus of claim 1 , further comprising;
a first auxiliary cathode disposed between the first organic functional layer and the second electrode; and
a second auxiliary cathode disposed between the second organic functional layer and the second electrode.
4. The organic light-emitting display apparatus of claim 3 , wherein the first auxiliary cathode and the second auxiliary cathode directly contact the second electrode.
5. The organic light-emitting display apparatus of claim 1 , wherein the second electrode is integrally disposed on the first organic functional layer and second organic functional layer.
6. The organic light-emitting display apparatus of claim 1 , wherein the first organic functional layer further comprises a side surface contacting the layer.
7. The organic light-emitting display apparatus of claim 1 , wherein the first organic functional layer further comprises a side surface contacting the layer contacting the top surface of the first first electrode.
8. The organic light-emitting display apparatus of claim 1 , wherein the second organic functional layer further comprises a side surface contacting the layer on the layer contacting the top surface of the second first electrode.
