    Abstract: A display device includes: a display region and a non-display region surrounding the display region; a first bending line defined on the display region, where the first bending line includes a portion extending in a first direction; a first region located at one side of the first bending line; a second region located at the other side of the first bending line and bent from the first region in one direction; a first alignment mark disposed in the first area and having a first area; and a second alignment mark disposed in the second area and facing toward the first alignment mark while the first bending line is disposed between the first and second alignment marks. The second alignment mark has a second area different from the first area.

    Abstract: A display device includes a front display area, a first side display area, a second side display area, a corner display area, a display panel, and a light guide member. The first side display area extends from a first side of the front display area. The second side display area extends from a second side of the front display area. The corner display area is disposed between the first side display area and the second side display area. The display panel overlaps the front display area and does not overlap the corner display area. The light guide member is disposed in the corner display area.
