A light valve 1, upon which an image is formed, is divided into two halves, each of which is separately projected onto a screen. The valve is illuminated by schematically illustrated light sources 2, and reflected light is passed through a projection lens system 3. The projected light beam is then split in two at the apex of double mirrors 4. Each half beam is reflected by mirrors 4 onto corresponding mirrors 5 which, in turn, reflect the light towards a screen 6 forming part of a light-tight box 7.
