## Abstract

A method of manufacturing a display device is provided. The display device includes a digitizer which is formed so that at least a part thereof is bent and a display panel which is installed along a shape of an outer surface of the digitizer.

## Claims

### Claim 1

A method of manufacturing a display device, the method comprising:
adhering a display panel to a digitizer, the digitizer formed of a flexible metal layer used for electromagnetic lamination, and comprising:
a first digitizer on which first lines are formed; and
a second digitizer on which second lines are formed, wherein the second lines are formed to cross the first lines; and thereafter
simultaneously bending at least a part of the digitizer and at least part of the display panel through a jig,
wherein when the jig applies a force to at least a part of the digitizer, a metal layer of the digitizer is plastically deformed to keep a bent state, and
wherein the display panel remains in a bent state due to its adherence to, and the plastic deformation of, the digitizer.

### Claim 2 (depends on 1)

The method of claim 1, further comprising
adhering the display panel onto an outer surface of the digitizer to keep a bent state of the display panel.

### Claim 3 (depends on 2)

The method of claim 2, further comprising
adhering the display panel and the digitizer to each other through an adhesive layer.

### Claim 4 (depends on 1)

The method of claim 1, further comprising
adhering an electromagnetic interference (EMI) shielding layer to the digitizer before the at least a part of the digitizer is bent through the jig.

### Claim 5 (depends on 4)

The method of claim 4 further comprising
adhering a flexible printed circuit (FPC) to the EMI shielding layer.

### Claim 6 (depends on 1)

The method of claim 1, wherein the display panel is flexible.
