Abstract

An organic light-emitting display apparatus including a substrate; a first electrode on the substrate; a pixel defining layer on the substrate, the pixel defining layer including an opening exposing a portion of the first electrode and corresponding to a pixel; an organic light-emitting layer disposed on the first pixel electrode in the opening; a second electrode on the pixel defining layer and the organic light-emitting layer; and an auxiliary electrode contacted on the second electrode, disposed on the pixel defining layer.

Claims (20)

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

a substrate;

a first electrode on the substrate;

a pixel defining layer on the substrate, the pixel defining layer including an opening exposing a portion of the first electrode and corresponding to a pixel;

an organic light-emitting layer disposed on the first pixel electrode in the opening;

a second electrode on the pixel defining layer and the organic light-emitting layer; and

an auxiliary electrode contacting the second electrode and disposed on the pixel defining layer,

wherein a portion of the second electrode overlapping the pixel defining layer is disposed between the pixel defining layer and the auxiliary electrode.

2. The organic light-emitting display apparatus of claim 1 , wherein the auxiliary electrode comprises at least one of aluminum (Al), silver (Ag), gold (Au), copper (Cu), and nickel (Ni).

3. The organic light-emitting display apparatus of claim 1 , wherein the auxiliary electrode comprises at least one of indium tin oxide (ITO), indium zinc oxide (IZO), ZnO, In 2 O 3 , indium gallium oxide (IGO), and aluminum zinc oxide (AZO).

4. The organic light-emitting display apparatus of claim 1 , wherein the auxiliary electrode comprises a light-absorbing material.

5. The organic light-emitting display apparatus of claim 1 , further comprising a light-absorbing material layer on the auxiliary electrode.

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

a substrate;

a first electrode on the substrate;

a pixel defining layer on the substrate, the pixel defining layer including an opening exposing a portion of the first electrode and corresponding to a pixel;

an organic light-emitting layer disposed on the first pixel electrode in the opening;

a second electrode on the pixel defining layer and the organic light-emitting layer; and

an auxiliary electrode contacting the second electrode and disposed on the pixel defining layer,

wherein the auxiliary electrode is disposed on a upper surface of the second electrode, and the pixel defining layer is disposed on a lower surface of the second electrode.
