Claim Text:
1. A method of manufacturing a display device, comprising: forming a thin film transistor on a substrate, the substrate including a pixel region; forming a light blocking member at a boundary of the pixel region; forming a pixel electrode in the pixel region, the pixel electrode connected to the thin film transistor; forming a sacrificial layer on the pixel electrode and the light blocking member; ashing the sacrificial layer; forming a common electrode on the sacrificial layer and the light blocking member; forming a roof layer on the common electrode, the roof layer comprising a color filter; forming an opening in the common electrode and the roof layer; forming a microcavity by removing the sacrificial layer through the opening; injecting a liquid crystal to fill the microcavity through the opening; and forming an overcoat to seal the opening.
