Abstract

A display device includes a display panel including a first panel and a second panel, the first panel being located at one side of the second panel in a first direction, a support member configured to support a bottom surface of the display panel and assist in a sliding motion of the display panel in the first direction, and a filling member covered by the first panel and the support member at an end of the first panel in the first direction, where the first panel includes a first portion, a second portion, and a third portion, the first portion covering one surface of the support member and in contact, at least partially, with the other surface of the support member and extending in the first direction, the second portion being at least partially opposing the first portion and extending in a direction opposite the first direction.

First claim

What is claimed is:

1 . A display device comprising:
a display panel comprising a first panel and a second panel, the first panel being located at one side of the second panel in a first direction; a support member configured to support a bottom surface of the display panel and assist in a sliding motion of the display panel in the first direction; and a filling member covered by the first panel and the support member at an end of the first panel in the first direction, wherein the first panel comprises a first portion, a second portion, and a third portion, the first portion covering one surface of the support member and in contact, at least partially, with an other surface of the support member and extending in the first direction, the second portion being at least partially opposing the first portion and extending in a direction opposite the first direction, and the third portion connecting the first portion and the second portion, wherein the support member overlaps the first portion and the third portion, and is in contact with the filling member, and wherein the support member comprises a first support part overlapping the first portion, a second support part overlapping the second portion, and a third support part overlapping the third portion, the second support part and the third support part being in contact with the filling member.

2 . The display device of claim 1 , wherein the first support part is in contact, at least partially, with the filling member.

3 . The display device of claim 2 , wherein a contact area between the filling member and the first support part is greater than a contact area between the filling member and the second support part.

4 . The display device of claim 1 , wherein the filling member comprises a first filling portion in contact with the support member and a second filling portion exposed from the support member, and wherein the second filling portion is covered by the first panel.

5 . The display device of claim 4 , wherein the first portion and the second portion of the first panel are parallel to each other.

6 . The display device of claim 5 , wherein the first panel further comprises a fourth portion and a fifth portion, the fourth portion being connected to the second portion and covers the second filling portion, the fifth portion being connected to the fourth portion and located opposite to the first portion with the first support part interposed therebetween, and the first portion, the second portion, and the fourth portion extend in different directions from one another.

7 . The display device of claim 6 , wherein the fourth portion extends in a second direction crossing the first direction and has a flat shape.

8 . The display device of claim 6 , further comprising an adhesive member between the fourth portion and the filling member.

9 . The display device of claim 6 , further comprising an integrated circuit opposite to the first support part on the fifth portion.

10 . A display device comprising:
a display panel comprising a first panel and a second panel, the first panel being located at one side of the second panel in a first direction; a support member configured to support a bottom surface of the display panel and assist in a sliding motion of the display panel in the first direction; and a filling member covered by the first panel and the support member at an end of the first panel in the first direction, wherein the first panel comprises a first portion, a second portion, and a third portion, the first portion covering one surface of the support member and in contact, at least partially, with an other surface of the support member and extending in the first direction, the second portion being at least partially opposing the first portion and extending in a direction opposite the first direction, and the third portion connecting the first portion and the second portion, wherein the support member overlaps the first portion and the third portion, and is in contact with the filling member, and wherein the support member comprises a first support part overlapping the first portion, a second support part overlapping the second portion, and a third support part overlapping the third portion, and wherein the third support part comprises a first curved portion curved with a first radius of curvature and a second curved portion connected to the first curved portion and curved with a second radius of curvature that is smaller than the first radius of curvature.

11 . The display device of claim 10 , wherein the filling member comprises a first filling portion in contact with the support member and a second filling portion exposed from the support member and a contact surface between the first filling portion, and the first curved portion has a curvature different from that of a contact surface between the first filling portion and the second curved portion.

12 . The display device of claim 10 , wherein a curvature of an overlapping portion between the third portion of the first panel and the first curved portion of the third support part is different from a curvature of an overlapping portion between the third portion of the first panel and the second curved portion.

13 . The display device of claim 10 , wherein the first support part and the second support part are parallel to each other and have a flat shape.

14 . A display device comprising:
a display panel comprising a first panel and a second panel, the first panel being located at one side of the second panel in a first direction; a support member configured to support a bottom surface of the display panel and assist in a sliding motion of the display panel in the first direction; and a filling member covered by the first panel and the support member at an end of the first panel in the first direction, wherein the first panel comprises a first portion, a second portion, and a third portion, the first portion covering one surface of the support member and in contact, at least partially, with an other surface of the support member and extending in the first direction, the second portion being at least partially opposing the first portion and extending in a direction opposite the first direction, and the third portion connecting the first portion and the second portion, wherein the support member overlaps the first portion and the third portion, and is in contact with the filling member, and wherein the first panel further comprises a fourth portion connected to the second portion and covers the filling member and a fifth portion connected to the fourth portion and located opposite to the first portion with the support member interposed therebetween, and the fourth portion extending in a second direction crossing the first direction and has a flat shape.

15 . The display device of claim 14 , further comprising a cover panel between the first panel and the support member.

16 . The display device of claim 15 , wherein the support member comprises a first support part overlapping the first portion, a second support part overlapping the second portion, and a third support part overlapping the third portion, and the cover panel covers the first support part and cover at least partially the third support part.
