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: Disclosed is a display device capable of reducing the reflection of external light. The display device includes an optical adhesive layer disposed between an element substrate, on which a light-emitting element and a touch sensor are disposed, and a cover substrate, wherein the optical adhesive layer includes a first lower adhesive layer disposed so as to overlap an emission area, in which the light-emitting element is disposed, and a second lower adhesive layer formed so as to have a shape different from the shape of the first lower adhesive layer, the second lower adhesive layer being disposed so as to overlap a non-emission area, excluding the emission area, whereby it is possible to improve optical efficiency while reducing the reflection of external light.

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.
