First claim
Opening claim text (preview).
What is claimed is: 1. A display device comprising: a protection film; and a display panel comprising a pixel, wherein the protection film comprises: a carrier film comprising a hydrophobic region and a hydrophilic region, and an adhesive layer on the carrier film and comprising a plurality of adhesive dots separated from each other, the adhesive dots being at the hydrophilic region of the carrier film, and areas of the carrier film between the adhesive dots being the hydrophobic region. 2. The display device of claim 1 , wherein the protection film further comprises a release film on the adhesive layer and configured to be detachable. 3. The display device of claim 1 , wherein the plurality of adhesive dots form an embossed texture. 4. The display device of claim 1 , wherein the carrier film comprises polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulfone (PES), and/or polyethylene (PE). 5. The display device of claim 4 , wherein the protection film is at one surface of the display panel. 6. The display device of claim 1 , wherein the pixel is configured to emit light. 7. A display device comprising: a protection film; and a display panel comprising a pixel, wherein the protection film comprises: a carrier film comprising a hydrophobic region and a hydrophilic region, and an adhesive layer on the carrier film and comprising a plurality of adhesive dots separated from each other, the adhesive dots being at the hydrophobic region of the carrier film, and areas of the carrier film between the adhesive dots being the hydrophilic region.
