Abstract
A stereoscopic image display system has a left/right stereoscopic image signal generator for alternately generating left-eye and right-eye image signals at every field, a screen for projecting image light, a liquid crystal shutter. The liquid crystal shutter has a response speed of 1 ms or less, and a contrast between black and white of 100 to 1 or more at a central wavelength of an emission spectrum of a CRT in both parallel and crossing modes of the polarizing plates of the shutter, and a cell gap of 3 .mu.m or less. The screen comprises a Fresnel lens and a lenticular sheet, and the lenticular sheet is disposed in a direction so that a polarizing condition does not generate a phase difference based on the lenticular sheet.
