ABSTRACT:
In a method of filling a liquid crystal display panel with liquid crystal and a liquid crystal filling system using the method, a seal line and spacers are formed on a color filter substrate. A first volume defined by the seal line and a second volumes defined by the spacers are obtained. An amount of liquid crystal to be supplied into a region enclosed by the seal line is precisely calculated based on the first and second volumes. Shortage of the liquid crystal supplied into the LCD panel and overflow of the liquid crystal can be avoided. Accordingly, the steps for supplying the liquid crystal into the LCD panel may be reduced, and simultaneously peripheral regions of the LCD panel be prevented from being contaminated by the liquid crystal while the liquid crystal is filled into the LCD panel.
