Abstract

Provided are an organic light-emitting display apparatus and a method of manufacturing the same. The organic light-emitting display apparatus includes: a substrate on which a display area is defined, wherein an image is displayed on the display area; a thin film transistor arranged on the display area of the substrate; a via-insulating layer covering the thin film transistor; a pixel electrode arranged on the via-insulating layer and electrically connected to the thin film transistor; a pixel-defining layer including an opening exposing a central portion of the pixel electrode, and covering an edge of the pixel electrode; a counter electrode facing the pixel electrode; an organic emission layer arranged between the pixel electrode and the counter electrode; a wire arranged on the via-insulating layer to be spaced apart from the pixel electrode and including a spacer area and a non-spacer area; and a spacer arranged on the spacer area.

Claims (35)

1. An organic light-emitting display apparatus comprising:

a substrate on which a display area is defined, wherein the display area is configured to display an image;

a thin film transistor arranged on the display area of the substrate;

a via-insulating layer covering the thin film transistor;

a pixel electrode arranged on the via-insulating layer and electrically connected to the thin film transistor;

a pixel-defining layer comprising an opening exposing a central portion of the pixel electrode, and covering an edge of the pixel electrode;

a counter electrode facing the pixel electrode;

an organic emission layer arranged between the pixel electrode and the counter electrode;

a wire arranged on the via-insulating layer to be spaced apart from the pixel electrode and comprising a spacer area and a non-spacer area; and

a spacer arranged on the spacer area,

wherein a height of the spacer from a top of the via-insulating layer is greater than a height of the pixel-defining layer from the top of the via-insulating layer.

2. The organic light-emitting display apparatus of claim 1 , wherein the spacer area has a greater width than the non-spacer area.

3. The organic light-emitting display apparatus of claim 1 , wherein the spacer is arranged on a same layer as the pixel-defining layer.

4. The organic light-emitting display apparatus of claim 1 , wherein the spacer comprises a same material as the pixel-defining layer.

5. The organic light-emitting display apparatus of claim 1 , wherein the spacer completely covers the spacer area, and an end of the spacer area is arranged between the via-insulating layer and the spacer.

6. The organic light-emitting display apparatus of claim 1 , wherein the wire comprises a contact hole, and the contact hole is spaced apart from the spacer area.

7. The organic light-emitting display apparatus of claim 1 , wherein the pixel-defining layer comprises a first inclination portion extending from an area where an upper surface of the pixel electrode contacts the opening, and a second inclination portion extending from the first inclination portion to an area of an upper surface of the via-insulating layer in a different inclination direction from the first inclination portion.

8. The organic light-emitting display apparatus of claim 1 , further comprising a wire-protection layer completely covering the non-spacer area of the wire and patterned to correspond to the non-spacer area.

9. The organic light-emitting display apparatus of claim 7 , wherein a first angle between the pixel electrode and the first inclination portion is greater than a second angle between the via-insulating layer and the second inclination portion.

10. The organic light-emitting display apparatus of claim 1 , further comprising a thin film encapsulation layer arranged on the counter electrode and comprising at least one inorganic layer and at least one organic layer.

11. The organic light-emitting display apparatus of claim 1 , wherein the pixel-defining layer comprises a photo-sensitive organic material.

12. An organic light-emitting display apparatus comprising:

a substrate on which a display area is defined, wherein the display area is configured to display an image;

a thin film transistor arranged on the display area of the substrate;

a via-insulating layer covering the thin film transistor;

a pixel electrode arranged on the via-insulating layer and electrically connected to the thin film transistor;

a pixel-defining layer comprising an opening exposing a central portion of the pixel electrode, and covering an edge of the pixel electrode;

a counter electrode facing the pixel electrode;

an organic emission layer arranged between the pixel electrode and the counter electrode;

a wire arranged on the via-insulating layer to be spaced apart from the pixel electrode and comprising a spacer area and a non-spacer area;

a spacer arranged on the spacer area; and

a wire-protection layer covering the non-spacer area of the wire,

wherein

the spacer is connected to the wire-protection layer and comprises a same material as the wire-protection layer.

13. The organic light-emitting display apparatus of claim 12 , wherein a height of the spacer is greater than a height of the wire-protection layer.
