Abstract

Provided is a flexible display apparatus having an improved light extracting efficiency and a method of manufacturing the flexible display apparatus. The flexible display apparatus includes a flexible substrate having a rippled surface, a pixel electrode on the flexible substrate and having a rippled surface, an intermediate layer on the pixel electrode and including a light emission layer, and an opposing electrode facing the pixel electrode. A method of manufacturing the flexible display apparatus includes applying a tensile force to a flexible substrate, forming a pixel electrode on the flexible substrate, removing the tensile force applied to the flexible substrate to form a rippled surface in the pixel electrode, forming an intermediate layer including an light emission layer on the pixel electrode, and forming an opposing electrode facing the pixel electrode.

Claims (18)

1. A method of manufacturing a flexible display apparatus, the method comprising:

applying a tensile force to a flexible substrate;

forming a pixel electrode on the flexible substrate;

removing the tensile force applied to the flexible substrate to form a rippled surface in the pixel electrode;

forming an intermediate layer comprising a light emission layer on the pixel electrode; and

forming an opposing electrode facing the pixel electrode.

2. The method of claim 1 , wherein the removing of the tensile force comprises forming irregularly spaced ripples in the pixel electrode.

3. The method of claim 1 , wherein the flexible substrate comprises an elastic material.

4. The method of claim 1 , wherein the forming of the intermediate layer comprising the light emission layer comprises using a deposition method or a printing method.

5. A method of manufacturing a flexible display apparatus, the method comprising:

applying a tensile force to a flexible substrate;

forming a pixel electrode on the flexible substrate;

forming an intermediate layer comprising a light emission layer on the pixel electrode;

forming an opposing electrode facing the pixel electrode; and

removing the tensile force applied to the flexible substrate to form a rippled surface in the pixel electrode.

6. The method of claim 5 , wherein the removing of the tensile force comprises forming irregularly spaced ripples in the pixel electrode.
