Abstract: A display device comprises a display area including a corner portion, a display panel including a non-display area located around the display area, and a cover window disposed on the display panel. The display panel includes a flexible substrate, and a crack propagation prevention pattern including a first organic layer disposed on the flexible substrate and directly contacting the flexible substrate. The intersecting point of a bending line overlaps with the crack propagation prevention pattern in the a thickness direction. In addition, the display device further includes alignment marks which overlap with the bending line.

Abstract: A display device includes a flexible substrate, a display element unit disposed on a first surface of the flexible substrate and including a thin-film transistor (TFT) and an organic light-emitting element coupled to the TFT, and a protective layer comprising an organic material and disposed directly on a second surface of the flexible substrate, the second surface being opposite to the first surface. Impact resistance of the display device can be strengthened by lowering of the neutral plane through the use of the protective layer.
