## Abstract

A display device is disclosed. The display device includes a plurality of support units disposed side by side on the rear surface of a flexible display panel, a resin unit, which is made of a resin, for elastically interconnecting the support units, and a restoration unit protruding from each support unit for interfering with the resin unit, which stretches when the display panel is bent, in order to restore the display panel to the original state thereof. The support units may be integrally formed with the resin unit in order to maintain the flatness of the display panel. In addition, when impact is applied to the display panel, the support units may distribute the impact to the periphery of the display panel, thereby preventing damage to the display panel.

## Claims

### Claim 1

A display device, comprising:
a plurality of support units disposed side by side on a rear surface of a display panel;
a plurality of restoration units, each restoration unit protruding from respective support units; and
a resin unit disposed on and between the plurality of support units and the plurality of restoration units for elastically interconnecting the support units and the restoration units;
wherein the restoration units interfere with the resin unit to restore the display panel to its original position when impact is applied to the display panel.

### Claim 2 (depends on 1)

The display device according to claim 1, wherein the restoration unit comprises a protruding member integrally protruding from an edge portion or a middle portion of the rear surface of each support unit.

### Claim 3 (depends on 2)

The display device according to claim 2, wherein the restoration unit comprises at least two protruding members provided on the rear surface of each support unit.

### Claim 4 (depends on 3)

The display device according to claim 3, wherein the at least two protruding members and each support unit are integrally provided to form a sectional shape of a polygon comprising at least a triangular shape.

### Claim 5 (depends on 2)

The display device according to claim 2, wherein the restoration unit comprises a first bent member bent from an end of the protruding member.

### Claim 6 (depends on 2)

The display device according to claim 2, wherein the restoration unit comprises:
a first bent member protruding from the protruding member toward one side; and
a second bent member protruding toward the other side opposite of the first bent member.

### Claim 7 (depends on 6)

The display device according to claim 6, wherein at least one of the first bent member or the second bent member extends to partially crossover to an adjacent support unit of the plurality.

### Claim 8 (depends on 6)

The display device according to claim 6, wherein the restoration unit further comprises a third bent member protruding further from the first bent member.

### Claim 9 (depends on 8)

The display device according to claim 8, wherein the third bent member protrudes from an end of the first bent member towards each support unit.

### Claim 10 (depends on 6)

The display device according to claim 6, wherein the first bent member protrudes toward one side being parallel to each support unit, and the second bent member protrudes toward the opposite side being parallel to each support unit.

### Claim 11 (depends on 6)

The display device according to claim 6, wherein the first bent member and the second bent member have different lengths, and
one of the first bent member and the second bent member that is longer has a length greater than half a length of each support unit.

### Claim 12 (depends on 1)

The display device according to claim 1, wherein each support unit and the restoration unit are integrally formed by dual injection molding.
