Abstract: The invention relates to a device for display an autostereoscopic image on a video screen (20) having a cylindrical lens array (10) disposed in front of it. The video screen (20) has pixels made up of p color points (RGB) placed horizontally side by side, the number of viewpoints for the autostereoscopic image is different from p.times.n (where n is a non-zero integer), and the lens array (10) has a pitch equal to the product of the pitch of the color points (R, G, B) multiplied by the number of viewpoints, e.g. four.
