Abstract: A display device includes a display panel, a window, and a window protection layer. The display panel includes a first non-folding region, a second non-folding region, and a folding region which is foldable and disposed between the first non-folding region and the second non-folding region. The first non-folding region, the second non-folding region, and the folding region each include light emitting regions in which light emitting elements respectively overlap and a non-light emitting region disposed between the light emitting regions. The window is disposed on the display panel. The window protection layer has at least one groove overlapping the folding region defined therein, and is disposed on the window. The groove overlaps the non-light emitting region of the folding region when viewed on a plane.
