Abstract
A display device includes a substrate including pixel areas, a thin-film transistor disposed on the substrate, a first insulating layer disposed on the thin-film transistor, a pixel electrode disposed on the first insulating layer and connected to the thin-film transistor, a liquid crystal layer filling a microcavity disposed on the pixel electrode, a common electrode spaced apart from the pixel electrode by the microcavity, a roof layer disposed on the common electrode, an injection hole disposed in the common electrode and the roof layer, the injection hole partially exposing the microcavity, a third insulating layer disposed on the roof layer, and an overcoat disposed on the third insulating layer and sealing the microcavity by covering the injection hole, wherein a first convex embossing pattern is formed on an upper surface of the third insulating layer.
