ABSTRACT:
There is provided a manufacturing method of a liquid crystal display panel. The manufacturing method includes the steps of manufacturing a panel having a cell gap by joining a substrate including a pressure-reducing port and an injection port to another substrate having no pressure-reducing and injection ports, injecting a liquid crystal material containing a liquid crystal and a polymer monomer into the cell gap, and curing the polymer monomer included in the cell gap, wherein the step of injecting a liquid crystal material is performed by applying pressure to the liquid crystal material using a pressure-applying apparatus, after reducing the inside pressure of the cell gap. Thus, the manufacture of a liquid crystal display panel is easy, and the waste of the liquid crystal material is minimized. Further, the optical properties of the fabricated panel are at least as excellent as those of a panel made by a conventional vacuum injection method or a conventional compression method.
