Abstract

An organic light-emitting display apparatus including a substrate, a first first electrode on the substrate, a first organic functional layer on the first first electrode, the first organic functional layer including a first emission layer, a first second electrode on the first organic functional layer, a second first electrode on the substrate, the second first electrode being spaced apart from the first first electrode, a second organic functional layer on the second first electrode, the second organic functional layer including a second emission layer, a second second electrode on the second organic functional layer, and a self-assembled layer between the first organic functional layer and the second organic functional layer, the self-assembled layer containing fluorine.

Claims (15)

1. An organic light-emitting display apparatus, comprising:

a substrate;

a first first electrode on the substrate;

a first functional layer on the first first electrode, the first functional layer including a first emission layer;

a first second electrode on the first functional layer;

a second first electrode on the substrate, the second first electrode being spaced apart from the first first electrode;

a second functional layer on the second first electrode, the second functional layer including a second emission layer;

a second second electrode on the second functional layer;

a pixel-defining layer including an insulating layer and covering an edge of the first first electrode and an edge of the second first electrode; and

a layer under the pixel-defining layer, the layer is formed of a material containing fluorine and surrounds peripheries of the first first electrode and the second first electrode, and the material containing fluorine is in direct contact with the first first electrode and the second first electrode.

2. The organic light-emitting display apparatus as claimed in claim 1 , wherein the layer overlaps end portions of the first first electrode and the second first electrode.

3. The organic light-emitting display apparatus as claimed in claim 1 , wherein the layer includes a fluorocarbon group (—CF3).

4. The organic light-emitting display apparatus as claimed in claim 1 , wherein the first first electrode and the second first electrode include a conductive oxide.

5. The organic light-emitting display apparatus as claimed in claim 4 , wherein the first first electrode and the second first electrode include at least one of indium tin oxide, indium zinc oxide, zinc oxide, indium oxide, indium gallium oxide, and aluminum zinc oxide.

6. The organic light-emitting display apparatus as claimed in claim 1 , further comprising a common electrode integrally formed on the first second electrode and the second second electrode.
