Patent ID: 8637894

Claim:
An organic light-emitting display apparatus, comprising: a light-emitting region including an organic light-emitting element, a thin-film transistor (TFT), and a capacitor; and a non-light-emitting region including a pad region connected to wiring of the light-emitting region, the pad region comprising: a protrusion layer including a plurality of protrusions formed on a substrate so as to protrude; a pad electrode including a pad lower electrode and a pad upper electrode, the pad lower electrode being arranged on the protrusions in a protrusion portion formed along a protrusion outline of the protrusion layer and a flat portion formed along the substrate, the pad upper electrode being formed on the flat portion of the pad lower electrode; a source/drain electrode layer formed on the pad upper electrode; an organic layer formed on the source/drain electrode layer, the protrusion portion being non-overlapped by the organic layer, the organic layer being an insulating layer that is at least 3 microns thick, the organic layer serving as a pixel defining layer by exposing a pixel electrode of the organic light emitting element; and a counter electrode layer formed directly on the pad lower electrode within the protrusion portion and on the organic layer within the flat portion of the pad region, the counter electrode being in direct contact with the pad lower electrode in each of the tops, bottoms and sidewalls of each of the protrusions to prevent the organic layer from delaminating by increasing a contact area between the counter electrode and the pad lower electrode.
