LIQUID CRYSTAL SHUTTER GLASSES

摘要

A liquid crystal shutter is disposed within the viewing angle of a person observing a display unit, and is controlled according to the time division display of the display unit. The liquid crystal shutter has an effective shutter area that can control the transmission or shielding of an incident light, and a light attenuating area positioned outside the effective shutter area, for attenuating the incident light. The liquid crystal shutter has a shielding function for light from the vicinity of the center, but has no shielding function for light from the surroundings, thereby limiting flickering otherwise felt by the observer.
