Abstract

An organic light-emitting display apparatus includes a pixel electrode with at least one opening; an intermediate layer disposed on the pixel electrode that includes an organic emission layer; an opposite electrode disposed on the intermediate layer; and a driving circuit that includes an upper conductive layer that overlaps the at least one opening of the pixel electrode in a plan view, and that is electrically connected to the pixel electrode.

Claims (22)

1. An organic light-emitting display apparatus comprising:

a pixel electrode that includes at least one opening, wherein the pixel electrode completely surrounds the at least one opening;

an intermediate layer disposed over the pixel electrode that includes an organic emission layer;

an opposite electrode disposed over the intermediate layer; and

a driving circuit that includes an upper conductive layer that overlaps the at least one opening of the pixel electrode in a plan view, and that is electrically connected to the pixel electrode.

2. The organic light-emitting display apparatus of claim 1 ,

wherein the pixel electrode is a reflective electrode, and

the opposite electrode is a transparent or translucent electrode.

3. The organic light-emitting display apparatus of claim 1 , wherein the pixel electrode includes a reflective layer that completely surrounds the at least one opening.

4. The organic light-emitting display apparatus of claim 1 , wherein the driving circuit further includes a lower conductive layer disposed below the upper conductive layer that overlaps the at least one opening in a plan view, and

the upper conductive layer and the lower conductive layer are electrically connected to each other.

5. The organic light-emitting display apparatus of claim 4 , wherein the driving circuit further includes at least one thin film transistor (TFT) and at least one capacitor, and

wherein the upper conductive layer and the lower conductive layer correspond to a node to which the at least one TFT and the at least one capacitor are connected.

6. The organic light-emitting display apparatus of claim 5 , wherein the at least one TFT comprises:

an active layer;

a gate electrode disposed on the active layer and insulated from the active layer; and

at least one of a source electrode and a drain electrode disposed on the gate electrode and electrically connected to the active layer,

wherein the upper conductive layer is a part of one of the source electrode and the drain electrode.

7. The organic light-emitting display apparatus of claim 6 , wherein the at least one capacitor comprises:

a first electrode disposed on a same layer as the gate electrode; and

a second electrode disposed on different layer from at least one of the source electrode and the drain electrode that is opposite to the first electrode with an insulating layer therebetween,

wherein one of the source electrode and the drain electrode is electrically connected to the second electrode through a contact hole in the insulating layer, and the lower conductive layer is a part of the second electrode.
