Stereoscopic television system

摘要

The present invention relates to a three-dimensional display which is provided with a display device 11 alternatively displaying an image for the right eye and an image for the left eye in division of the images at predetermined time period and a liquid crystal shutter 17 disposed in front of the display device 11, the liquid crystal shutter 17 is operated in synchronization with image switching of the display device 11, and the image transmitted through the liquid crystal shutter 17 is observed as a three-dimensional image through polarized glasses 14 of which polarizing directions differ in the right and left from each other. The liquid crystal cell 13 which serves as a liquid crystal shutter 17 has a structure that a ferroelectric liquid crystal is 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 is disposed, and the retardation plate 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 ¦ DELTA n1d1 - DELTA n2d2 ¦ </=50nm in the range of light wavelength from 400nm through 900nm, for the retardation ( DELTA n1d1) of the retardation plate and a retardation ( DELTA n2d2) of a liquid crystal cell forming the liquid crystal shutter. <IMAGE>
