PROBLEM TO BE SOLVED: To improve a receiving performance of a signal for driving a liquid crystal shutter in a three-dimensional video display system in which a viewer is enabled to perform three-dimensional viewing by alternately displaying a right-eye video image and a left-eye video image on a screen in a fixed term and using eyeglasses with liquid crystal shutters which the viewer wears to perform transmission and no transmission in a right-eye liquid crystal and a left-eye liquid crystal synchronously to the fixed term.SOLUTION: Liquid crystal shutter eyeglasses 100 comprise a transmission signal control section 103 and a signal transmitter 104, and a synchronizing signal of liquid crystal shutter drive equal to other liquid crystal shutter eyeglasses 110 is transmitted from first liquid crystal shutter eyeglasses to second and third liquid crystal shutter eyeglasses. Therefore, eyeglasses which are unlikely to receive a signal of liquid crystal shutter drive because of an obstacle or an angle is enabled to perform liquid crystal shutter drive, thereby enlarging a reception range of liquid crystal shutter eyeglasses as a whole. |
