Display device
A display device includes a display panel, and a protection film on the display panel and including a base film, and a plurality of protrusions on the base film.
1. A display device comprising:
a display panel comprising:
a first substrate;
a display element on the first substrate; and
an encapsulation member configured to isolate the display element from an external environment; and
a protection film on the display panel such that the display element is between the encapsulation member and the protection film, and comprising:
a base film; and
a plurality of protrusions on the base film.
2. The display device of claim 1 , wherein the protrusions are on a surface of the base film opposite the display panel.
3. The display device of claim 2 , wherein widths of the protrusions are about 10 μm to about 500 μm.
4. The display device of claim 3 , wherein heights of the protrusions are about 1 to about 20 times the widths of the protrusions.
5. The display device of claim 4 , wherein the heights of the protrusions are less than about 500 μm.
6. The display device of claim 3 , wherein a distance between adjacent ones of the protrusions is about 3 to about 20 times the widths of the protrusions.
7. The display device of claim 6 , wherein a distance between the adjacent ones of protrusions is less than about 500 μm.
8. The display device of claim 3 , wherein the protection film is on a side of the display panel opposite to a surface of the display panel from which light is emitted.
9. The display device of claim 1 , wherein the display element comprises:
a first electrode;
an organic layer on the first electrode; and
a second electrode on the organic layer.
10. The display device of claim 9 , wherein the encapsulation member comprises:
a plurality of inorganic layers; and
a plurality of organic layers alternately laminated with the plurality of inorganic layers,
wherein a lowermost one of the inorganic layers is on the display element.
11. The display device of claim 1 , wherein a cross-section of one of the protrusions parallel to a surface of the base film comprises at least one of a polygonal shape, a circular shape, or an oval shape.
12. The display device of claim 1 , wherein the base film comprises an elastic material.
13. The display device of claim 12 , wherein the base film comprises at least one of polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polypropylene (PP), polycarbonate (PC), polystyrene (PS), polysulfone (Psul), ployethylene (PE), polyphthalamide (PPA), polyethersulfone (PES), polyarylate (PAR), or a modified polyphenylene oxide (MPPO).
14. The display device of claim 1 , further comprising an adhesive layer between the display panel and the protection film.
