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.
