The aim is to improve the bending resistance a display device. The display device in one embodiment includes a substrate including a first surface and a second surface and a curved part between the first surface and the second surface, a display element arranged on the first surface, a conducting layer connected with the display element and extending to the second surface from the first surface via the curved part, a plurality of protective layers having a lower ductility than the substrate and arranged in the substrate side and/or opposite side to the substrate side with respect to the conducting layer and along the curved part, wherein each of the plurality of protective layers spreading over the curved part, to a certain region of the first surface side from the curved part, and to a certain region of the second side from the curved part.
