Abstract: A liquid crystal dispensing apparatus dispenses liquid crystal onto a substrate. The liquid crystal dispensing apparatus includes a frame, a table, at least one liquid crystal discharge device, and a liquid crystal amount inspecting portion. The table is installed on the frame to have the substrate to be mounted thereon. The liquid crystal discharge device adjustably discharges an amount of liquid crystal, and the liquid crystal amount inspecting portion inspects a liquid crystal dispensing amount by comparing an actual amount of liquid crystal discharged from the liquid crystal discharge device with a preset liquid crystal amount. The liquid crystal discharge device includes a piston to perform ascending motions to draw in the liquid crystal and descending motions to discharge the liquid crystal with an angle of at least a portion of the liquid crystal discharge device determining a magnitude of the ascending/descending motion to control an amount of liquid crystal discharged.
