The present invention relates to a supercooling system and a method for displaying a supercooled state which can accurately display a supercooled state of a stored object in spite of the external influence. The supercooling system includes a cooling apparatus including a storing unit storing a stored object, a cooling means cooling the storing unit, and a main control unit receiving external commercial power and controlling the cooling means to maintain the temperature in the storing unit at a temperature below at least the maximum ice crystal formation zone, and a supercooling apparatus including an independent storage room having a storing space therein to store an object and mounted and cooled in the storing unit, a temperature sensing unit sensing the temperature of the independent storage room, a temperature control means mounted in the independent storage room and controlling the internal temperature, a display unit displaying the state of the current control, and a sub-control unit controlling the temperature control means based on the sensed temperature from the temperature sensing unit to store the object received in the independent storage room in a supercooled state, and displaying the state of the stored object on the display unit with the proceeding of the cooling of the stored object or the storing space.
