PURPOSE: Liquid crystal shutter glasses are provided to support both an infrared ray communication method and a Bluetooth communication method. CONSTITUTION: A receiving unit includes an infrared ray communication module and a Bluetooth communication module. The receiving unit receives a 3D image signal by communicating with a 3D display device. A control unit(20) controls operations of right/left eye liquid crystals of liquid crystal shutter glasses by a signal transmitted from the receiving unit. The control unit determines whether the signal received from the 3D image display device is an infrared ray communication signal or a Bluetooth communication signal. The liquid crystal shutter glasses comprise an infrared ray signal processing unit and a Bluetooth signal processing unit.
