  • Patent number: 11985884
    Abstract: A display device prevents cracks from spreading to an active area. The display device includes a substrate including an active area and a non-active area having a bending area, a thin-film transistor disposed in the active area, a light-emitting element disposed in the active area and connected to the thin-film transistor, an encapsulation layer disposed on the light-emitting element, a touch sensor disposed on the encapsulation layer, a touch pad disposed in the non-active area, a first routing line connecting the touch sensor to the touch pad via a second routing line in the bending area, and a crack prevention layer disposed on the second routing line in the bending area. Thus, the crack prevention layer is capable of preventing the occurrence of cracks in the bending area BA, thus preventing cracks from spreading to the active area AA.
