Abstract: A method of manufacturing a liquid crystal display includes: forming a sacrificial layer by stacking a non-photosensitive resin; initiating formation of an etch stop layer on the sacrificial layer; forming a photoresist pattern; completing the etch stop layer using the photoresist pattern; ashing the photoresist pattern and the sacrificial layer by using the completed etch stop layer as a mask; forming a microcavity by removing the sacrificial layer; and forming a liquid crystal layer in the microcavity. The horizontal area occupied by the sacrificial layer is reduced by forming the common electrode or the etch stop layer at an upper side, thereby increasing the aperture ratio. Further, the vertical electric field is generated without distortion by horizontally forming the common electrode on the sacrificial layer and forming no common electrode on the sidewall thereof.
