Abstract
Disclosed is a method of manufacturing a liquid crystal display device using a liquid crystal dispensation alignment method which includes steps of: removing inorganic ions and the like by performing a vacuum drying process on substrates after cleaning alignment layers on which a rubbing process has been performed; and removing foreign objects by performing any one of a process for sucking up foreign objects by use of a nozzle having a specialized shape and a process for blasting a gas to which ultrasonic waves have been applied against the foreign objects, before liquid crystal is dispensed. In addition, a temperature at which sealing material is cured completely is lowered in order to inhibit activation (migration) of organic matters and to thereby reduce visible defects such as alignment bright defects.
