Claim Text:
1. A method of manufacturing a display device, comprising: forming a thin-film transistor on a substrate comprising a pixel area; forming a pixel electrode in the pixel area; forming a sacrificial layer on the pixel electrode; forming a common electrode covering an upper surface, a left surface, and a right surface of the sacrificial layer; forming a roof layer on the common electrode; forming a liquid crystal injection hole by patterning the roof layer and the common electrode and exposing the sacrificial layer on an upper edge of the pixel area and a lower edge of the pixel area; removing the sacrificial layer to form a space between the pixel electrode and the common electrode; injecting liquid crystal molecules into the space through the liquid crystal injection hole; and forming an overcoat on the roof layer, wherein the roof layer and the common electrode are patterned such that the roof layer and the common electrode comprise a protrusion protruding from at least one of the upper edge and the lower edge of the pixel area such that a portion of the liquid crystal injection hole is formed outside of the pixel area corresponding to the protrusion, wherein the protrusion extends in a direction away from the pixel area, beyond a gate line, and into an adjacent pixel area, wherein the gate line separates the pixel area and the adjacent pixel area.
