## Abstract

A display device, and a method and apparatus for manufacturing the display device, are provided. The display device includes a cover window including a curved portion, and a display panel smaller in at least one of length or width than the cover window and laminated on a flat portion of the cover window.

## Claims

### Claim 1

A display device comprising:
a cover window comprising a curved portion; and
a display panel smaller in at least one of length or width than the cover window and laminated on a flat portion of the cover window.

### Claim 2 (depends on 1)

The display device of claim 1, further comprising an adhesive layer between the display panel and the cover window.

### Claim 3 (depends on 1)

The display device of claim 1, wherein the flat portion extends from the curved portion.

### Claim 4 (depends on 3)

The display device of claim 3, wherein the display panel is laminated entirely on the flat portion.

### Claim 5 (depends on 3)

The display device of claim 3, wherein the curved portion comprises a plurality of curved portions.

### Claim 6 (depends on 3)

The display device of claim 3, wherein the display panel comprises:
a first display panel portion laminated on the flat portion; and
a second display panel portion extending in a curved shape from the first display panel portion and laminated on the curved portion.

### Claim 7 (depends on 1)

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

### Claim 8

A method of manufacturing a display device, the method comprising:
mounting a cover window comprising a curved portion to a first jig comprising a curved portion;
mounting a display panel, to which an adhesive layer is applied, to a second jig that conforms to a surface of the first jig; and
laminating the cover window to the display panel by using an actuator connected to one of the first jig or the second jig to move the one of the first jig or the second jig to another of the first jig or the second jig.

### Claim 9 (depends on 8)

The method of claim 8, wherein the display panel contacts a flat surface of the second jig.

### Claim 10 (depends on 8)

The method of claim 8, wherein the display panel is bent along an outer surface of the second jig during the mounting of the display panel to the second jig.

### Claim 11 (depends on 8)

The method of claim 8, wherein the display panel is smaller in at least one of length or width than the cover window.

### Claim 12 (depends on 8)

The method of claim 8, wherein
the display panel and the adhesive layer are flat during the mounting of the display panel to the second jig, and
the laminating of the cover window to the display panel comprises partially curving the display panel and the adhesive layer by the moving of the one of the first jig or the second jig.

### Claim 13 (depends on 8)

The method of claim 8, wherein the one of the first jig or the second jig is above the other of the first jig or the second jig, or the other of the first jig or the second jig is above the one of the first jig or the second jig.

### Claim 14 (depends on 8)

The method of claim 8, wherein the mounting of the display panel comprises fixing the display panel to the second jig.

### Claim 15 (depends on 8)

The method of claim 8, wherein the display panel is flexible.

### Claim 16

An apparatus for manufacturing a display device, the apparatus comprising:
a first jig comprising a mount surface that is partially curved to conform to a surface of a cover window of the display device;
a second jig comprising a surface conforming to the mount surface and configured to contact a display panel of the display device to which an adhesive layer is applied; and
an actuator connected to one of the first jig or the second jig and configured to move the one of the first jig or the second jig.

### Claim 17 (depends on 16)

The apparatus of claim 16, wherein
the first jig further comprises a first fixing unit for fixing the cover window to the mount surface, or
the second jig further comprises a second fixing unit for fixing the display panel to the surface conforming to the mount surface.

### Claim 18 (depends on 17)

The apparatus of claim 17, wherein the first fixing unit or the second fixing unit comprises:
an absorption unit; and
a driving unit for evacuating air from the absorption unit.

### Claim 19 (depends on 16)

The apparatus of claim 16, wherein at least one of the first jig or the second jig further comprises a cushion unit at an outer surface of the at least one of the first jig or the second jig.

### Claim 20 (depends on 19)

The apparatus of claim 19, wherein
the cushion unit comprises a plurality of cushion units at respective ends of the first jig or the second jig, and
a distance between the cushion units is less than at least one of length or width of the display panel.

### Claim 21 (depends on 16)

The apparatus of claim 16, further comprising a clamping unit spaced from the second jig and configured to support the display panel to which the adhesive layer is applied.

### Claim 22 (depends on 21)

The apparatus of claim 21, wherein
the clamping unit comprises a plurality of clamping units, and
a distance between the clamping units is less than at least one of length or width of the display panel when the clamping units support the display panel.

### Claim 23 (depends on 21)

The apparatus of claim 21, further comprising a driving unit coupled to the clamping unit and configured to linearly move the clamping unit.

### Claim 24 (depends on 23)

The apparatus of claim 23, wherein the driving unit is further configured to linearly move the clamping unit in a vertical direction of the second jig.

### Claim 25 (depends on 23)

The apparatus of claim 23, wherein the driving unit is further configured to linearly move the clamping unit in a diagonal direction of the second jig.

### Claim 26 (depends on 21)

The apparatus of claim 21, wherein at least one of the first jig or the second jig further comprises a cushion unit at an outer surface of the at least one of the first jig or the second jig.
