Abstract
A liquid crystal display includes a thin film transistor disposed on a substrate, a pixel electrode connected to the thin film transistor, a lower insulating layer disposed facing the pixel electrode, a roof layer disposed on the lower insulating layer, and a microcavity formed between the pixel electrode and the lower insulating layer. The microcavity includes a liquid crystal layer including a liquid crystal material. The liquid crystal display further includes a first groove formed between a first pixel area and a second pixel area, a second groove formed between the first pixel area and a third pixel area, wherein the first groove is covered by the roof layer, the second groove is exposed at a portion where the roof layer is removed, the first pixel area corresponds to the pixel electrode, and the first pixel area is disposed between the second pixel area and the third pixel area.
