Abstract: Disclosed is a display device capable of being manufactured through a simplified process and having improved touch sensitivity. The display device includes an encapsulation unit disposed on a light-emitting element, a touch sensor disposed on the encapsulation unit, and an intermediate layer disposed between the encapsulation unit and the touch sensor. The intermediate layer includes a first intermediate layer, having a dielectric constant that is lower than a dielectric constant of an organic film disposed above or under the intermediate layer, and a second intermediate layer, having greater hardness than the first intermediate layer, whereby touch sensitivity is improved while processing is simplified.

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.

Abstract: The present disclosure relates to a display device for improving productivity. The display device having a touch sensor is configured such that the total thickness of at least one inorganic insulation layer disposed on the region above each of dams is different from the total thickness of the at least one inorganic insulation layer disposed on a trench region between the dams. Thus, a photoresist for forming a routing line is formed so as to have a uniform thickness on the region above each of the dams and the trench region between the dams, and thus productivity is improved.
