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.
