Abstract:
The present invention relates to a method for cutting a liquid crystal display panel and a method for manufacturing a liquid crystal display panel having a desired size using the same. In a method for cutting a liquid crystal display panel which includes an upper panel to which a color filter is formed and a lower filter on which a thin film transistor is formed, the upper panel and the lower panel are respectively cut in such a way that a cut edge of the upper panel is outwardly protruded from a cut edge of the lower panel so that a step is formed at a cut surface between the upper panel and the lower panel. Since the cut edge of the upper panel is upwardly protruded from the cut edge of the lower panel, electrodes, signal lines, thin film transistors of the lower panel can be prevented from being damaged by the contact with the dispenser or by the pressure of the sprayed sealant while the sealant is formed after the cutting.
