A 3D image display device includes: a display unit (11) displaying left-eye and right-eye images alternately in a time-sharing manner; a display-side polarizing plate (12) arranged on the side of a display surface of the display unit; and shutter glasses having left-eye and right-eye shutters (2L,2R), opening and closing the left-eye and right-eye shutters in accordance with display states of images on the display unit. Each of the left-eye and right-eye shutters includes a liquid crystal cell (20), a retardation plate arranged at the liquid crystal cell on the side of the display unit (22), and a first glasses-side polarizing plate (21) 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 to each other and the polarization axis of the display-side polarizing plate and a retardation axis of the retardation plate are parallel or orthogonal to each other.
