PURPOSE: A duty ratio controlling method of liquid crystal shutter glasses is provided to control duty ratio of left-eye/right-eye liquid crystal by transmitting a synchronization signal for controlling operation of /right-eye liquid crystal. CONSTITUTION: The time of (T3-T1) is added to T1 time. A T3 signal section is generated in an IR signal receiver of a glasses side. The left liquid crystal off time is increased as reference time. The right liquid crystal off time is increased as the reference time.
