Abstract

A display device includes a display panel, a protective film, and an adhesive member. The display panel includes a non-bending area and a bending area configured to bend from the non-bending area, and the bending area includes a curvature area with a curvature and a facing area facing the non-bending area. The protective film is on a rear surface of the display panel, and includes a first surface facing the rear surface of the display panel and a second surface opposite to the first surface. The protective film has a groove corresponding to the curvature area. The adhesive member is between the protective film and the display panel, and a hydrophobic layer is on the second surface of the protective film, and is adjacent to the groove.

Claims (11)

1. A display device comprising:

a display panel comprising a non-bending area and a bending area configured to bend from the non-bending area, the bending area comprising a curvature area with a curvature and a facing area configured to face the non-bending area;

a protective film on a rear surface of the display panel, the protective film comprising a first surface configured to face the rear surface of the display panel and a second surface opposite to the first surface, the protective film having a groove corresponding to the curvature area;

an adhesive member between the protective film and the display panel; and

a hydrophobic layer on the second surface of the protective film, the hydrophobic layer comprising a first hydrophobic layer at a first side of the groove and a second hydrophobic layer at a second side of the groove, wherein the first hydrophobic layer and the second hydrophobic layer face each other when the facing area faces the non-bending area.

2. The display device of claim 1 , wherein the second surface of the protective film comprises a first rear surface and a second rear surface and the groove is between the first and second rear surfaces, and the protective film further comprises a first inner side surface extending from the first rear surface to define the groove and a second inner side surface extending from the second rear surface to define the groove.

3. The display device of claim 2 , wherein

the first hydrophobic layer is on the first rear surface, the first hydrophobic layer being adjacent to the first inner side surface; and

the second hydrophobic layer on the second rear surface, the second hydrophobic layer being adjacent to the second inner side surface.

4. The display device of claim 3 , wherein the groove extends in a first direction, and each of the first and second hydrophobic layers extends along the first direction.

5. The display device of claim 1 , wherein the hydrophobic layer comprises one of manganese oxide (MnO2) polystyrene, zinc oxide (ZnO) polystyrene, precipitated calcium carbonate, carbon nanotube, silica, and fluoropolymer.
