## Abstract

A display device includes: a display panel; a resin layer on the display panel and having a first protrusion having a first style on a surface thereof; a first window on the resin layer and having a second protrusion having a second style on a surface thereof; and a second window on the first window.

## Claims

### Claim 1

A display device comprising:
a display panel;
a resin layer on the display panel and having a first protrusion having a first style on a surface thereof;
a first window on the resin layer and having a second protrusion having a second style on a surface thereof; and
a second window on the first window.

### Claim 2 (depends on 1)

The display device of claim 1, wherein
the resin layer, the first window, and the second window comprise a first area for displaying an image, a second area that is curved and around the first area, and a third area at a side of the display panel.

### Claim 3 (depends on 2)

The display device of claim 2, wherein
a cross-section of the first style is generally triangular, and
a cross-section of the second style is generally semi-circular.

### Claim 4 (depends on 3)

The display device of claim 3, wherein
the first protrusion is at the first area.

### Claim 5 (depends on 4)

The display device of claim 4, wherein
the resin layer further comprises a third protrusion having the second style at the second area.

### Claim 6 (depends on 3)

The display device of claim 3, wherein
a height and a width of the first protrusion are in a range of 10 micrometers (μm) to 30 μm.

### Claim 7 (depends on 3)

The display device of claim 3, wherein
a height and a width of the second protrusion are in a range of 1 micrometer (μm) to 100 μm.

### Claim 8 (depends on 1)

The display device of claim 1, wherein
refractive indexes of the resin layer and the first window are different from each other.

### Claim 9 (depends on 1)

The display device of claim 1, wherein
the resin layer further comprises scattered particles.

### Claim 10 (depends on 1)

The display device of claim 1, wherein
the resin layer comprises one or more layers comprising at least one of polycarbonate (PC), polymethylmethacrylate (PMMA), cyclic olefin polymer (COP), polyarylate (PAR), polyethersulfone (PES), polyethylene terephthalate (PET), and polyethylene naphthalate (PEN).

### Claim 11 (depends on 1)

The display device of claim 1, wherein
the first window comprises one or more layers comprising at least one of polycarbonate (PC), polymethylmethacrylate (PMMA), polyarylate (PAR), polyethersulfone (PES), polyethylene terephthalate (PET), and polyethylene naphthalate (PEN), and
the second window comprises glass or silplus.

### Claim 12 (depends on 1)

The display device of claim 1, wherein
the display panel comprises an organic light emitting element.
