Abstract: A method of manufacturing a liquid crystal display panel. The method includes: preparing a substrate; forming a sacrificial pattern including a negative photoresist material on the substrate; forming a loop portion to cover top and side surfaces of the sacrificial pattern and to expose one side surface of the sacrificial pattern; forming a cavity defined as a predetermined region in the loop portion by performing a strip process on the exposed side surface of the sacrificial pattern by using (utilizing) a strip solution and removing the sacrificial pattern; forming a liquid crystal layer by injecting liquid crystal in the cavity; and forming a blocking member to cover a surface of the cavity into which the liquid crystal is injected.
