A stereoscopic video display system is disclosed, in which an interlaced scanning picture information for a viewer's left eye and an interlaced scanning picture information for the viewer's right eye are doubled in frequency and displayed alternately on a monitor display at the field rate. Also, left and right visual fields of the viewer are shut off alternately by glasses with a shutter mechanism in synchronism with a field period and a start time point and an end time point of the vertical deflection are selected properly in such a manner that the monitor display may carry out the interlaced scannings for each of the left eye and the right eye. Thus, the left and right pictures are displayed in the interlaced scanning manner, respectively and the quality of the reproduced picture will have superior clarity and characteristics.
