Abstract: A display device includes a flexible substrate including a bending area corresponding to an area at which the display device is bent, and a first area and a second area which is spaced apart from the first area by the bending area, a display element unit disposed in the first area of the flexible substrate; and a buffer member disposed in the bending area of the flexible substrate. The buffer member in the bending area includes: a first buffer member having a first maximum thickness, and a second buffer member having a second maximum thickness which is smaller than the first maximum thickness. Among the first buffer member and the second member, the first buffer member disposed closer to the first area and the second member disposed closer to the second area.

Abstract: A manufacturing method of a display device includes: forming pixels on a mother substrate including a display area and a non-display area; attaching a polarization film stretched in a first direction and a second direction opposite to the first direction on the mother substrate having the pixels thereon; and cutting at least a portion of the polarization film along a third direction, wherein the third direction forms an acute angle with the first direction toward an outside of the polarization film.

Abstract: A display device includes: a substrate; pixels on the substrate; and a polarization film on the pixels and stretched in a first direction and a second direction opposite to the first direction. The polarization film is cut at an end portion of the polarization film along a third direction, the third direction forming an acute angle with the first direction toward an outside of the polarization film.

Abstract: A display device includes a substrate including a plastic layer, a barrier layer, and a display area in which an image is displayed. The display device further includes a light-emitting diode disposed in the display area, a planarization layer, and a pixel definition layer. The planarization layer and the pixel definition layer overlap the light-emitting diode. The display device further includes a thin film encapsulation layer disposed on the pixel definition layer. The thin film encapsulation layer includes at least one inorganic layer. The display device further includes an opening disposed in the display area and penetrating the substrate. The opening includes a protruded portion and a depressed portion, and the barrier layer overlaps at least one of the pixel definition layer and the planarization layer at the protruded portion.
