Abstract

A display device having a display panel including first to third regions. The second region and the third region are respectively connected to opposite sides of the first region. The third region is bendable. A flexible circuit board is connected to an end of the third region. A first protection layer overlaps the first region to third regions. A second protection layer overlaps at least a portion of the third region. A support member overlaps the first protection layer. The support member includes a plurality of openings. The first protection layer includes a first groove overlapping at least a portion of the second region and a second groove overlapping at least a portion of the third region. Each of the first groove and the second groove overlaps the support member.

Claims (54)

1 . A display device comprising:

a display panel including first to third regions, the second region and the third region are respectively connected to opposite sides of the first region, the third region is bendable;

a flexible circuit board connected to an end of the third region;

a first protection layer overlapping the first region to third regions;

a second protection layer overlapping at least a portion of the third region; and

a support member overlapping the first protection layer, the support member including a plurality of openings,

wherein the first protection layer includes a first groove overlapping at least a portion of the second region and a second groove overlapping at least a portion of the third region, and

each of the first groove and the second groove overlaps the support member.

2 . The display device of claim 1 , wherein the second region of the display panel is a rollable or slidable region.

3 . The display device of claim 1 , wherein:

the third region includes a bending region; and

the third region is in a bent state so that at least a portion of the third region is positioned on a rear surface of the display panel.

4 . The display device of claim 1 , wherein the second protection layer includes at least one third groove.

5 . The display device of claim 4 , wherein the plurality of openings included in the support member includes a first opening overlapping at least portion of the first groove, and a second opening overlapping at least portion of the second groove.

6 . The display device of claim 5 , wherein the third groove overlaps at least a portion of the second opening.

7 . The display device of claim 4 , wherein a cross-section of each of the first to third grooves has a shape in which a width thereof becomes narrower in a direction towards the display panel.

8 . The display device of claim 4 , wherein a height of each of the first to third grooves is in a range of about 30 μm to about 90 μm.

9 . The display device of claim 1 , wherein:

the plurality of openings included in the support member include a plurality of first openings overlapping the second region and a plurality of second openings overlapping the third region;

the first groove overlaps at least two first openings; and

the second groove overlaps at least two second openings.

10 . The display device of claim 9 , wherein the second protection layer includes a third groove overlapping at least two second openings.

11 . The display device of claim 10 , wherein:

a width of the first groove is greater than a width of the plurality of first openings; and

widths of the second groove and the third groove are greater than a width of the plurality of second openings.

12 . The display device of claim 10 , further comprising:

a first auxiliary member overlapping the first groove;

a second auxiliary member overlapping the second groove; and

a third auxiliary member overlapping the third groove.

13 . The display device of claim 12 , further comprising:

a barrier layer positioned between the third region of the display panel and the support member,

wherein the first auxiliary member is integrally formed with the barrier layer, and

the second auxiliary member is integrally formed with the support member.

14 . The display device of claim 12 , further comprising:

an adhesive layer positioned between the support member and the second region of the display panel,

wherein the third auxiliary member is integrally formed with the adhesive layer.

15 . A display device comprising:

a display panel including a display area and a non-display area;

a flexible circuit board connected to an end of the non-display area;

a first protection layer overlapping the display area and at least a portion of the non-display area;

a second protection layer overlapping at least a portion of the non-display area; and

a first support member and a second support member overlapping the first protection layer, the first and second support members including a plurality of openings,

wherein the first protection layer includes a first groove overlapping the first support member and a second groove overlapping the second support member.

16 . The display device of claim 15 , wherein:

the display area includes a first area and a second area overlapping the first support member; and

the non-display area includes a third area overlapping the second support member.

17 . The display device of claim 16 , wherein the second protection layer includes a third groove overlapping the third area.

18 . The display device of claim 17 , wherein a width of each of the first groove to the third groove decreases in a direction towards the display panel in a cross-sectional view.

19 . The display device of claim 16 , wherein:

the first support member includes a plurality of first openings,

the second support member includes a plurality of second openings,

the first groove overlaps at least one first opening, and

the second groove overlaps at least one second opening.

20 . The display device of claim 19 , wherein the first groove and the at least one first opening have a same shape in a plan view.
