Abstract: A display device is disclosed, which may increase the number of lines arranged in a bending area and at the same time may minimize a crack generated in the bending area. The display device comprises a display area in which pixels are arranged, and a non-display area surrounding the display area, provided with a bending area within the non-display area; a plurality of first lines arranged in the bending area and electrically connected with the pixels; a first organic film arranged on the first lines; a plurality of second lines arranged on the first organic film in the bending area and electrically connected with the pixels; and a second organic film arranged on the second lines, wherein at least one of the first organic film and the second organic film is provided with an open area.

Abstract: A display device includes a display panel having a display area and a non-display area, crack lines disposed in the non-display area; and a first crack pad and a second crack pad connected to both ends of the crack lines. The crack lines comprise a plurality of crack line units connected to each other. Each of the plurality of crack line units comprises a plurality of sub-crack lines connected in parallel. In this manner, the efficiency of inspecting for cracks can be improved.

Abstract: A display device is disclosed, which may prevent an inorganic film formed in an organic film open area from being damaged and prevent a cathode electrode from being shorted. The display device includes a substrate including a display area on which pixels area arranged, and a non-display area surrounding the display area; a first metal layer formed in the non-display area of the substrate; at least one insulating film arranged on the first metal layer; a second metal layer arranged on the at least one insulating film and connected with the first metal layer through a contact hole that passes through the at least one insulating film formed in the non-display area; a cover layer arranged on the contact hole and formed to overlap the contact hole; and an encapsulation film formed to cover the display area and the cover layer.
