ABSTRACT:
Disclosed is a method of cutting a liquid crystal display (LCD) unit cell from an LCD assembly panel. The method includes applying a coolant onto heated cutting path formed on the LCD assembly panel. A rapidly heated portion of the substrate is rapidly cooled using water having a high specific heat or a mixed coolant in which a material for improving characteristics of surface tension, viscosity and thermal conductivity is dissolved in water. Therefore, the cutting quality of the substrate is improved, and a cutting speed is also enhanced.
