Abstract
Disclosed is an organic light emitting display apparatus in which an anode electrode, an organic emission layer, a cathode electrode, and an auxiliary electrode connected to the cathode electrode and disposed on the same layer as that of the anode electrode are disposed in an active area of the substrate, a signal pad and a pad electrode connected to the signal pad and covering a top of the signal pad are disposed in a pad area of the substrate, and a top of the pad electrode has lower oxidation rate than the top of the signal pad.
Claims11
An organic light emitting display apparatus, comprising:
- a substrate including an active area and a pad area;
- an anode electrode in the active area of the substrate;
- an organic emission layer on the anode electrode;
- a cathode electrode on the organic emission layer;
- an auxiliary electrode on a same layer as the anode electrode and connected to the cathode electrode;
- a signal pad in the pad area of the substrate;
- and
- a pad electrode connected to the signal pad through a contact hole and covering a top of the signal pad,
- wherein a top of the pad electrode has a lower oxidation rate than the top of the signal pad,
- wherein the signal pad comprises a lower signal pad and an upper signal pad,
- wherein an oxidation rate of the lower signal pad is lower than an oxidation rate of the upper signal pad, and
- wherein a resistance of the upper signal pad is lower than a resistance of the lower signal pad.
