1. A liquid crystal dispensing apparatus, comprising: a container to contain liquid crystal; a discharge pump unit coupled to the container, the discharge pump unit including a case, 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 nozzle unit separably coupled to the discharge pump unit to dispense liquid crystal from the discharge pump onto a substrate, wherein the case includes a cap, first and second cases formed of a metal and at least two bottom surfaces formed of a fluorine resin separably coupled to each other, and the second case coupled to the at least two bottom surfaces includes a suction opening and a discharge opening through which liquid crystal is drawn in and discharged as the piston moves inside the cylinder, the cap being disposed at one end portion of the first case and the at least two bottom surfaces being disposed at another end portion of the second case opposing to the end portion of the first case coupled to the container.
