Abstract:
A 3D image display device. The device may include: a display unit displaying left-eye and right-eye images alternately; a display-side polarizing plate arranged on the side of a display surface of the display unit; and shutter glasses having left-eye and right-eye shutters, and opening and closing a shutter in accordance with display states of images on the display unit. A shutter includes a liquid crystal cell, a retardation plate arranged at the liquid crystal cell, and a first glasses-side polarizing plate arranged at the liquid crystal cell on the side opposite to the retardation plate. Polarization axes of the display-side polarizing plate and the first glasses-side polarizing plate are orthogonal. The polarization axis of the display-side polarizing plate and a retardation axis of the retardation plate are parallel or orthogonal.
