Abstract

An organic light-emitting display apparatus includes: a substrate including an emission region and a non-emission region and having a recess formed in at least a portion of the non-emission region; a black matrix disposed in the recess; a thin film transistor disposed on the non-emission region of the substrate and including an active layer, a gate electrode, and source and drain electrodes; a pixel electrode disposed on the emission region of the substrate and electrically connected to one of the source and drain electrodes; an organic emission layer disposed on the pixel electrode; and an opposite electrode disposed on the organic emission layer.

Claims (47)

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

a substrate including an emission region and a non-emission region, and having a recess formed in at least a portion of the non-emission region;

an opposite electrode disposed on the organic emission layer; and

an adhesive member disposed between and spatially completely separating the substrate and the black matrix.

2. The organic light-emitting display apparatus of claim 1 , wherein the recess is formed throughout the non-emission region.

3. The organic light-emitting display apparatus of claim 1 , wherein the recess is formed in a surface facing the thin film transistor.

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

a substrate including an emission region and a non-emission region, and having a recess formed in at least a portion of the non-emission region;

a black matrix disposed in the recess;

a thin film transistor disposed in the non-emission region of the substrate, and including an active layer, a gate electrode, a source electrode and a drain electrode;

a pixel electrode disposed in the emission region of the substrate and electrically connected to one of the source electrode and the drain electrode;

an organic emission layer disposed on the pixel electrode; and

an opposite electrode disposed on the organic emission layer;

wherein the recess is formed in a surface of the substrate opposite to a surface of the substrate facing the thin film transistor.

5. The organic light-emitting display apparatus of claim 1 , thickness of the black matrix planarizes the recess.

6. The organic light-emitting display apparatus of claim 1 , wherein the black matrix comprises one of an organic material and an organic-inorganic hybrid material.

7. The organic light-emitting display apparatus of claim 1 , wherein the non-emission region comprises a non-display region corresponding to an edge region of the substrate.

8. The organic light-emitting display apparatus of claim 7 , wherein the recess is only formed in the non-display region.

9. A method of manufacturing an organic light-emitting display apparatus, the method comprising the steps of:

forming a recess in at least a portion of a non-emission region of a substrate which includes an emission region and the non-emission region;

forming a black matrix in the recess;

forming a thin film transistor, including an active layer, a gate electrode, a source electrode and a drain electrode, on the non-emission region of the substrate;

forming a pixel electrode which is electrically connected to one of the source electrode and the drain electrode;
