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.

Abstract: The present disclosure provides a display device with a display panel, an input sensing unit, and a protective member. The input sensing unit is disposed on the display panel. The protective member includes an insulating material and is disposed on the input sensing unit. The protective member includes a first protective portion and a second protective portion disposed on the first protective portion, where a first modulus of the first protective portion is greater than a second modulus of the second protective portion. The second protective portion with the lower modulus absorbs external impacts, and the first protective portion with the higher modulus disperses the absorbed impact and prevents the display panel from being deformed by an external force. Therefore, the impact resistance of the display device is improved.
