Abstract

The organic light emitting diode display may comprise a cover window including a display region and a non-display region that surrounds the display region; a flexible substrate arranged on a lower portion of the cover window, and including a first region that is spaced apart from the cover window and a second region that extends from the first region toward the cover window; and an adhesive layer arranged between the cover window and the flexible substrate to make the cover window and the flexible substrate adhere to each other.

First claim

What is claimed is:

1. An organic light emitting diode display, comprising:
a cover window located in a first plane and comprising a display region and a non-display region surrounding the display region;
a flexible substrate disposed on a lower side of the cover window, and comprising a first region spaced apart from the cover window and a second region extending from the first region toward the first plane, wherein the flexible substrate comprises a composite substrate of a display substrate of a display panel assembly, and further comprises organic light emitting elements and a base substrate arranged on a lower face of the display panel assembly;
a first adhesive layer arranged between the cover window and the flexible substrate configured to adhere the cover window and the flexible substrate to each other, and
a second adhesive layer disposed between the display substrate and the base substrate
wherein the first region is located in a second plane which is parallel to the first plane.

2. The organic light emitting diode display of claim 1 , wherein the flexible substrate is a display substrate comprising a display panel assembly, the display panel assembly comprising organic light emitting elements.

3. The organic light emitting diode display of claim 1 , wherein the flexible substrate is disposed on a lower face of a display panel assembly, the display panel assembly comprising organic light emitting elements.

4. The organic light emitting diode display of claim 1 , further comprising a polarizing element disposed between the cover window and the flexible substrate.

5. The organic light emitting diode display of claim 1 , further comprising a touch panel disposed between the cover window and the flexible substrate.

6. The organic light emitting diode display of claim 5 , further comprising a polarizing element disposed between the cover window and the touch panel.

7. The organic light emitting diode display of claim 1 , wherein the first adhesive layer comprises an extension portion extending to a space between the cover window and the first region of the flexible substrate in the same plane.
