Abstract:
A liquid crystal display includes a substrate and a thin film transistor disposed on the substrate. A pixel electrode is connected to the thin film transistor. A roof layer faces the pixel electrode. A plurality of microcavities are disposed between the pixel electrode and the roof layer. A first microcavity is filled with a liquid crystal material. A first injection hole and a second injection hole are disposed at edges of the first microcavity. According to the present invention, a height of the first injection hole is different from a height of the second injection hole. A plurality of grooves extend in a direction parallel to a top surface of the substrate and are disposed between the plurality of microcavities. According to the present invention, an alignment material layer is disposed in one of the grooves.
