## Abstract

A method of manufacturing a display apparatus includes: preparing a window, where the window includes a rear protection film, a window substrate, a front protection film, and a carrier film; removing the rear protection film and attaching a lower structure of the display apparatus to the window substrate; and removing the carrier protection film.

## Claims

### Claim 1

A method of manufacturing a display apparatus, the method comprising:
preparing a window, wherein the window includes a rear protection film, a window substrate, a front protection film, and a carrier protection film;
removing the rear protection film and attaching a lower structure of the display apparatus to the window substrate; and
removing the carrier protection film.

### Claim 2 (depends on 1)

The method of claim 1, wherein the front protection film comprises a first adhesive layer and a first base film.

### Claim 3 (depends on 2)

The method of claim 2, wherein the front protection film further comprises at least one selected from a first antistatic layer and a second antistatic layer.

### Claim 4 (depends on 2)

The method of claim 2, wherein a thickness of the first base film is in a range of about 70 μm to about 130 μm.

### Claim 5 (depends on 2)

The method of claim 2, wherein a release force of the front protection film is in a range of about 12 g·f/inch to about 30 g·f/inch.

### Claim 6 (depends on 2)

The method of claim 2, wherein a surface resistance of the front protection film is in a range of about 105 Ω/sq to about 1011 Ω/sq.

### Claim 7 (depends on 2)

The method of claim 2, wherein the window further comprises a second adhesive layer, a film layer, and a hard coating layer, which are arranged between the window substrate and the front protection film.

### Claim 8 (depends on 7)

The method of claim 7, wherein the first adhesive layer is attached to the hard coating layer.

### Claim 9 (depends on 1)

The method of claim 1, wherein the carrier protection film comprises a third adhesive layer and a second base film.

### Claim 10 (depends on 9)

The method of claim 9, wherein the carrier protection film further comprises at least one selected from a third antistatic layer and a fourth antistatic layer.

### Claim 11 (depends on 9)

The method of claim 9, wherein a thickness of the second base film is in a range of about 35 μm to 65 μm.

### Claim 12 (depends on 9)

The method of claim 9, wherein a thickness of the third adhesive layer is in a range of about 10 μm to about 20 μm.

### Claim 13 (depends on 9)

The method of claim 9, wherein a release force of the carrier protection film is in a range of about 5 g·f/inch to about 15 g·f/inch.

### Claim 14 (depends on 9)

The method of claim 9, wherein a surface resistance of the carrier protection film is in a range of about 105 Ω/sq to about 1011 Ω/sq.
