Abstract: The inventive concept provides a liquid crystal display including an insulation substrate; a roof layer which is formed on the insulation substrate; a pixel electrode which is formed on the insulation substrate and under the microcavity supported by the roof layer; and a liquid crystal layer which is disposed in the microcavity. The opening corresponding to unit microcavity includes portions having a first width and a second width. According to the inventive concept, configurations of the pixel and the opening which may minimize the remaining liquid crystal are provided to adjust a size of the liquid crystal injection hole between a plurality of microcavities into which the liquid crystal is injected, which may prevent an orientation error of the liquid crystal caused by the remaining liquid crystal outside the microcavity and thus prevent the display error.
