## 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.

## Claims

### Claim 1

An organic light emitting diode display, comprising:
a cover window comprising a display region and a non-display surrounding the display region;
a flexible substrate disposed on a lower side of the cover window, spaced apart from the cover window, and comprising a first region and a second region extending from the first region; and
a sealing agent filling a space between the second region of the flexible substrate and the cover window.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 5)

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

### Claim 7 (depends on 1)

The organic light emitting diode display of claim 1, further comprising an adhesive layer configured to adhere an element that is disposed between the cover window and the flexible substrate to the cover window.

### Claim 8 (depends on 7)

The organic light emitting diode display of claim 7, the adhesive layer comprising:
a first face directly adhering to the cover window;
a second face opposite the first face; and
a side face extending from the second face to connect the first face and the second face, the side face being covered by the sealing agent.

### Claim 9 (depends on 7)

The organic light emitting diode display of claim 7, the adhesive layer comprising:
a first face of the adhesive layer directly adhering to the cover window;
a second face opposite the first face directly adhering to an element disposed between the cover window and the flexible substrate; and
a side face extending from the second face to connect the first face and the second face, the side face being covered by the sealing agent.
