ABSTRACT:
A liquid crystal dispensing apparatus includes a container containing liquid crystal material; a discharge pump drawing in and discharging the liquid crystal material; a nozzle dispensing, onto a substrate, liquid crystal material discharged by the discharge pump; and a detector arranged near the nozzle to detect the presence of residual liquid crystal material accumulated on the surface of the nozzle. When the presence of residual liquid crystal material is detected, a dummy dispensing operation and/or a cleaning operation may be performed to remove the residual liquid crystal material.
