Display device and method thereof

A display device comprising:

• a display panel including a first region, a second region, and a bending region disposed between the first region and the second region and having a predetermined radius of curvature;
• a functional layer disposed on the display panel and overlapping the first region;
• and
• a bending protection layer disposed on the display panel and overlapping the bending region;
• wherein the functional layer includes a functional layer side surface facing the bending protection layer,
• the bending protection layer includes a bending protection layer side surface facing the functional layer side surface,
• the first region operates in any one of a folding mode which enables folding around a folding axis and a non-folding mode which enables unfolding to be flat,
• in the folding mode, the bending protection layer side surface is aligned with the functional layer side surface,
• in the non-folding mode, the bending protection layer side surface is spaced apart from the functional layer side surface, and
• a shape of the bending protection layer side surface is aligned with a shape of the functional layer side surface

A method for manufacturing a display device, the method comprising:

• providing a display panel including a first region, a second region, and a bending region disposed between the first region and the second region and having a predetermined radius of curvature;
• providing an adhesive layer onto the display panel to overlap the first region;
• providing a functional layer onto the adhesive layer to overlap the first region;
• folding the first region with respect to a folding axis to make the adhesive layer and the functional layer slip in a first direction that is a direction of the bending region;
• providing a bending protection resin onto a side surface of the adhesive layer that has slipped and a side surface of the functional layer that has slipped and curing the bending protection resin to form a bending protection cured product;
• and
• non-folding the first region to move the adhesive layer and the functional layer in a second direction opposite to the first direction and form a bending protection layer.

A display device comprising:

• a folding region at which the display device is foldable;
• a display panel including a first region corresponding to the folding region, and a bending region extended from the first region and at which the display panel is folded;
• an adhesive layer on the display panel, and overlapping the folding region the first region;
• a functional layer on the adhesive layer, and overlapping the folding region and the first region;
• and
• a bending protection layer on the display panel and overlapping the bending region;
• wherein the display device which is unfolded at the folding region, disposes:
• the adhesive layer in contact with the bending protection layer, and
• the functional layer spaced apart from the bending protection layer.

A display device comprising:

• a folding region at which the display device is foldable;
• a display panel including a first region corresponding to the folding region, and a bending region extended from the first region and at which the display panel is folded;
• a functional layer on the display panel and overlapping the folding region and the first region;
• and
• a bending protection layer on the display panel and overlapping the bending region;
• wherein
• the functional layer includes a functional layer side surface facing the bending protection layer,
• the bending protection layer includes a bending protection layer side surface facing the functional layer side surface,
• the display device which is folded at the folding region, disposes the bending protection layer side surface contacting the functional layer side surface, and
• the display device which is unfolded at the folding region, disposes the bending protection layer side surface spaced apart from the functional layer side surface.

A method for providing a display device, the method comprising:

• providing a display panel including a first region corresponding to a folding region of an unfolded display device, and a bending region which is extended from the first region in a first direction and at which the display panel is bent;
• providing on the display panel which is bent, in the unfolded display device:
• an adhesive layer overlapping the folding region;
• and
• a functional layer on the adhesive layer and overlapping the folding region;
• folding the display panel which is bent, together with the adhesive layer and the functional layer, at the folding region, to define a folded display device, wherein the folding both:
• slides the adhesive layer and the functional layer together with each other, along the display panel, and in the first direction, and
• disposes each of the adhesive layer and the functional layer which is slid, to include a side surface closest to the bending region;
• providing a cured first bending protection resin onto the side surface of the adhesive layer and the side surface of the functional layer, within the folded display device, to provide a bending protection layer of the display device;
• and
• unfolding the display panel which is bent, together with the adhesive layer and the functional layer, at the folding region, to provide the display device, wherein the unfolding slides the adhesive layer and the functional layer together with each other, along the display panel, and in a second direction opposite to the first direction.
