Display device having folding area
A display device includes: a display module; a plate on one surface of the display module; and an adhesive layer between the display module and the plate, wherein the plate includes a folding area and a folding peripheral area, the folding area of the plate includes a plurality of grooves, and the adhesive layer overlaps a portion of the folding area.
1 . A display device comprising:
a display module;
a plate on one surface of the display module; and
an adhesive layer between the display module and the plate,
wherein the plate includes a folding area and a folding peripheral area,
the folding area of the plate includes a plurality of grooves, and
the adhesive layer extends continuously across at least a first one of the plurality of grooves between the display module and the plate to overlap a first portion of the folding area and does not overlap at least a second one of the plurality of grooves at a second portion of the folding area in a plan view,
the plurality of grooves are positioned along a first direction,
the display device is folded in a second direction perpendicular to the first direction, and
a ratio of a length in the second direction of the folding area overlapping the adhesive layer to a length in the second direction of the folding area is in a range of 30% to 60%.
2 . The display device of claim 1 , wherein
the adhesive layer includes areas spaced apart from each other in the second direction, and
the areas spaced apart from each other overlap the folding area.
3 . The display device of claim 2 , wherein
a length in the second direction of the adhesive layer including the areas spaced apart from each other is shorter than a length in the second direction of an area where a groove is formed.
4 . The display device of claim 1 , wherein
the plate further includes a groove in a non-folding area.
5 . The display device of claim 1 , further comprising
a protective member between the display module and the adhesive layer.
6 . The display device of claim 1 , wherein the plurality of grooves are spaced apart from each other in the first direction and the second direction.
7 . The display device of claim 1 , further comprising
a digitizer on an other surface of the plate.
8 . A display device comprising:
a display module;
a plate on one surface of the display module; and
an adhesive layer between the display module and the plate,
wherein the plate includes a folding area and a folding peripheral area,
the folding area of the plate includes a plurality of grooves,
the adhesive layer extends continuously across at least a first one of the plurality of grooves between the display module and the plate to overlap a first portion of the plurality of grooves in the folding area and does not overlap at least a second one of the plurality of grooves at a second portion of the plurality of grooves in the folding area in a plan view, and
the adhesive layer includes a plurality of grooves overlapping the folding area,
the plurality of grooves are positioned along a first direction,
the display device is folded in a second direction perpendicular to the first direction, and
a ratio of a length in the second direction of the folding area overlapping the adhesive layer to a length in the second direction of the folding area is in a range of 30% to 60%.
9 . The display device of claim 8 , wherein
a groove of the adhesive layer overlaps a groove of the plate.
10 . The display device of claim 8 , wherein
a groove of the adhesive layer includes an area that does not overlap a groove of the plate.
11 . The display device of claim 8 , wherein the plurality of grooves of the adhesive layer are positioned along the first direction, and the display device is folded in a second direction perpendicular to the first direction.
12 . The display device of claim 8 , wherein the plurality of grooves of the plate are spaced apart from each other in the first direction and the second direction.
13 . The display device of claim 8 , wherein the plurality of grooves of the adhesive layer are spaced apart from each other in the first direction and the second direction.
14 . The display device of claim 8 , further comprising
a protective member between the display module and the adhesive layer.
15 . The display device of claim 8 , further comprising
a digitizer on an other surface of the plate.
16 . The display device of claim 8 , wherein
the plate further includes a groove in a non-folding area.
