A liquid crystal display comprising:
- a substrate;
- a gate line and a data line crossing each other formed on the substrate;
- a thin film transistor connected to the gate line and the data line;
- a pixel electrode connected to the thin film transistor and having a slit at a center;
- a liquid crystal layer filling a plurality of microcavities positioned on the pixel electrode;
- a common electrode positioned on the liquid crystal layer;
- and
- a roof layer formed on the common electrode and having an oblique portion formed to be inclined at both sides of the microcavities.
A method for manufacturing a liquid crystal display, comprising:
- forming a thin film transistor on a substrate;
- forming a pixel electrode connected to the thin film transistor and including a slit at a center;
- forming a sacrificial layer on the pixel electrode;
- forming a common electrode on the sacrificial layer;
- forming a roof layer including an oblique portion formed to be inclined at both sides outside the microcavities on the common electrode;
- patterning the roof layer to expose a portion of the sacrificial layer to form a liquid crystal injection hole;
- removing the sacrificial layer to form microcavities between the pixel electrode and the common electrode;
- injecting a liquid crystal material into the microcavities through the liquid crystal injection hole to form a liquid crystal layer;
- and
- forming an overcoat roof layer to seal the microcavities.
