Abstract: A display apparatus may include a base substrate including a first portion and a second portion smaller than the first portion, a plurality of pixels disposed on the first portion, a protection substrate disposed below the base substrate, and a groove disposed in a portion of the protection substrate and overlapped with the second portion. The groove may include a first region extending in a first direction, and a second region and a third region, which are arranged along the first direction, wherein the first region is interposed between the second region and the third region. The first and second portions may be arranged in a second direction crossing the first direction, and a width of each of the second and third regions may be larger than a first width of the first region, when measured in the second direction.

Abstract: A display device includes a substrate in which a first area, a second area and a bending area between the first and second areas are defined, a plurality of pixels disposed above the substrate in the first area, a plurality of conductive layers extending to and intersecting the bending area, a protective film covering the conductive layers and disposed in the bending area, a first portion of the first area adjacent to the bending area, and a second portion of the second area adjacent to the bending area. The display device further includes a plurality of tag layers disposed in the first and second portions and connected to both ends of the conductive layers, wherein the bending area is interposed between the plurality of tag layers. The tag layers are exposed to an outside of the display device by exposure holes defined in the protective film.
