A display panel includes a first portion including a display area; a second portion adjacent to the first portion in a first direction; and a bendable portion connecting the first and second portions and at which the display panel is bent about a bending axis extending in a second direction perpendicular to the first direction. The bendable portion includes: a stress concentration portion to which a stress is applied; and first and second stress generation portions at opposing sides of the stress concentration portion in the first direction, and to which stress is applied less than that applied to the stress concentration portion. Each of the first and second stress generation portions defines a second width in the second direction, the stress concentration portion defines a third width in the second direction less than the second width, and the second width is less than the first width.
