摘要：
A liquid crystal dispensing apparatus includes a container to contain liquid crystal, a discharge pump, and a nozzle to dispense liquid crystal from the discharge pump onto a substrate. The discharge pump has a separably formed case, a cylinder received in the case, a piston inserted into the cylinder and having a groove at a lower portion such that the piston draws in and discharges liquid crystal by rotating and moving up-down, and a suction opening and a discharge opening through which liquid crystal is to be respectively drawn in and discharged as the piston is moved.
