The system comprises a flat screen (1) whose color triplets of pixels (Pi,Pj) are orientated horizontally, a mask (2) formed by groups of occultation elements (Gi,Gj) placed in front of the screen, a network of lenses (Li,Lj) where each is associated with one or more columns of triplets of pixels, an oculometer (7) locating the position of eyes, left and right (OG,OD), of an observer (S) with respect to the screen. This further provides the position information, that is coordinates (xOG,yOG,xOD,yOD), and a control circuit (4) receiving the position information and generating the control signals for controlling the occultation elements (Ei1,Ei2,Ei3,Ej1,Ej2,Ej3) of triplets to release them as a function of the instantaneous position of the observer. Each group of occultation elements (Gi,Gj) is associated with a column of triplets of pixels for occultating them and they are displayed only by the control of the corresponding occultation elements. The mask (2) is formed as an optical switching device distributed in groups of surface elements constituting the occultation elements. The optical switching device is of type liquid crystals. The mask (2) is constituted by pixels in portions individually controlled and constituting the parts of a pixel to occultate or to display. The pixels are subdivided by subdividing the counter-electrode common to all pixels. The subdivision is in column. The occultation elements are extruded in all column of pixels and the control is by one or two extremities. The columns of pixels (Pi,Pj) are associated with images (IMD,IMG) for the right eye and the left eye, respectively. The network of lenses (3) contains one lens per column of pixels.
