Abstract

A display device includes a display panel, a frame disposed on a back surface of the display panel, slidable plate disposed to overlap, at least in part, the frame, a slidable structure includes a plurality of roll belts, and a support guide disposed between the frame and the slidable plate. Each of the plurality of roll belts includes a bar extending in a straight line and a ring extending from one surface of the bar and providing an accommodation hole to which the support guide is coupled.

First claim

What is claimed is:

1 . A display device, comprising:
a display panel including a first area, a second area and a third area between the first area and the second area; a frame disposed on a back surface of the display panel to overlap the first area; a slidable plate disposed to overlap, at least in part, the frame and configured to slide in a first mode and a second mode; a slidable structure whose one side is connected to a side surface of the frame and which includes a plurality of roll belts which overlaps the third area and is spaced apart from each other at a predetermined distance in one direction on the back surface of the display panel; and a support guide disposed between the frame and the slidable plate, wherein each of the plurality of roll belts includes a bar extending in a straight line and a ring extending from one surface of the bar and providing an accommodation hole to which the support guide is coupled.

2 . The display device according to claim 1 , wherein the slidable plate is composed of a first slidable plate disposed on a back surface of the frame and a second slidable plate disposed on a back surface of the first slidable plate, and
the other side of the slidable structure is connected to a side surface of the second slidable plate.

3 . The display device according to claim 2 , wherein each of one surface of the frame and one surface of the first slidable plate in contact with the one surface of the frame includes a groove where the support guide is accommodated.

4 . The display device according to claim 3 , wherein the support guide is fixed to the groove of the first slidable plate, and wherein the support guide is pulled into the groove of the frame or withdrawn from the groove of the frame when the first slidable plate is slid into the first mode or the second mode.

5 . The display device according to claim 2 , wherein the first area is fixed to the frame and the second area is fixed to a back surface of the second slidable plate.

6 . The display device according to claim 1 , further comprising:
a rotation shaft which is rotatably disposed on one side surface of the slidable plate, wherein the slidable plate is slid in the first mode or the second mode according to a rotation direction of the rotation shaft.

7 . The display device according to claim 6 , wherein the rotation shaft includes a first part having a first diameter and a second part having a second diameter smaller than the first diameter, and
a width of the second part is equal to a width of the support guide, and the support guide is coupled to the second part.

8 . The display device according to claim 6 , wherein:
the plurality of roll belts are disposed on the rotation shaft so as to wrap around at least a part of the rotation shaft, and the slidable structure including the plurality of roll belts and the slidable plate are slid into the first mode or the second mode according to a rotation direction of the rotation shaft.

9 . The display device according to claim 1 , wherein in the first mode, the slidable plate is pulled into the frame and the first area is exposed to outside, and
in the second mode, the slidable plate is withdrawn from the frame and the first area and the third area are exposed to the outside.

10 . The display device according to claim 1 , wherein the support guide coupled to the accommodation hole has a “C” shape.

11 . The display device according to claim 1 , wherein an edge of the support guide coupled to the accommodation hole has a wedge shape.

12 . The display device according to claim 1 , wherein the plurality of roll belts includes a plurality of rings each providing the accommodation hole to which the support guide is coupled.

13 . The display device according to claim 1 , further comprising:
a support member disposed under the display panel to support the display panel, wherein the support member includes a first support member disposed under the display panel and a second support member disposed under the first support member, and the second support member includes a plurality of holes in an area overlapping the third area.

14 . The display device according to claim 13 , further comprising:
an adhesive disposed in an area where the second support member overlaps the third area, wherein the adhesive has a same shape as the plurality of roll belts, and wherein the part of the second support member including the plurality of holes is bonded to the slidable structure including the plurality of roll belts by the adhesive.
