PROBLEM TO BE SOLVED: To adequately decide time to carry out a maintenance service for components constituting a device for injecting a liquid crystal and time to replace them in the device for injecting the liquid crystal even when a liquid crystal panel for liquid crystal injection and a liquid crystal material are different in some cases. SOLUTION: The device 1 for injecting the liquid crystal comprises a vacuum chamber 10 to carry out liquid crystal injection treatment therein, a liquid crystal storing vessel 11 placed in the vacuum chamber 10, a valve 12 to regulate pressure inside the vacuum chamber 10, the preceding stage pump 13 of a vacuum pump to exhaust air inside the vacuum chamber 10, further a following pump 14 on the downstream of the preceding stage pump 13 to exhaust air inside the vacuum chamber 10, a sensor 15 to detect a state inside the vacuum chamber 10 and so on. In addition to the constitution mentioned above, an input means 3, a storage means 3, a discrimination means 5, a read means 6, and a display means 7 are provided to the device 1. The storage means 3 and the discrimination means 5 carry out determination of the time to carry out the maintenance service for the respective components, such as valves and pumps, constituting the device for injecting the liquid crystal, time to replace them, time to clean the vacuum chamber and the time to carry out the maintenance service for sensors.
