A three-dimensional display is provided with a display device alternatively displaying an image for the right eye and an image for the left eye in division of the images at predetermined time periods. A liquid crystal shutter disposed in front of the display device is operated in synchronization with image switching of the display device, and the image transmitted through the liquid crystal shutter is observed as a three-dimensional image through polarized glasses of which polarizing directions differ in the right and left from each other. The liquid crystal cell which serves as a liquid crystal shutter has a structure of a ferroelectric liquid crystal held between two sheets of resin film substrates and the ferroelectric liquid crystal contains more than 10 wt % of ferroelectric liquid crystal polymer so that it can respond to a large size display device and a high speed motion. A retardation plate to compensate elliptical polarization of the polarized glasses prevents lowering of contrast of the display due to the elliptical polarization peculiar to the operation mode of the liquid crystal cell and reduces a double reflection of the image, by setting the condition of &verbar;&Dgr;n,d,&minus;&Dgr;n,d,&verbar;&lE;50 nm in the range of light wavelength from 400 nm through 900 nm, for the retardation (&Dgr;n,d,) of the retardation plate and a retardation (&Dgr;n,d,) of a liquid crystal cell forming the liquid crystal shutter.
