ABSTRACT:
A liquid crystal dispensing apparatus facilitating detection of vapor within liquid crystal material, facilitating removal of residual liquid crystal material, and facilitating precise control of predetermined dispensing positions and dispensing amounts includes a container containing liquid crystal material, a discharge pump drawing in and discharging liquid crystal material, and a nozzle dispensing liquid crystal material, discharged from the discharge pump, onto a substrate. The discharge pump includes a case, a window at a lower portion of the case, a cylinder within the case, a piston rotatably arranged within the cylinder and having a groove for drawing in and discharging liquid crystal material, and a suction opening and a discharge opening through which liquid crystal material is drawn into and discharged from with respect to the cylinder.
