ABSTRACT:
Disclosed is a method of testing a liquid crystal display device enabling a quick test by determining a test of a liquid crystal panel according to a liquid crystal filling state of the liquid crystal panel. The method includes: checking a liquid crystal filling state of a liquid crystal panel for a defective liquid crystal filling state; and executing a test of a liquid crystal panel having a defective liquid crystal filling state. The process for testing a liquid crystal filling state may include detecting a dispensed amount of liquid crystal dropped using a liquid crystal dispensing apparatus or may include measuring the weight of liquid crystal dropped. Other methods of identifying the filling state of the liquid crystal panel may be used.
