Abstract: A method of manufacturing a display apparatus includes preparing a substrate including a display area and a pad area outside of the display area, forming a sacrificial layer in the pad area, forming an encapsulation layer over the display area and the pad area, forming cracks in at least a portion of the encapsulation layer by increasing a volume of the sacrificial layer or by gasifying or evaporating at least a portion of the sacrificial layer, and removing at least a portion of the encapsulation layer in the pad area. A display apparatus is manufactured according to the manufacturing method.

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.
