A liquid crystal image forming projector includes a liquid crystal display selectively operable for affecting light incident thereon, and an optical device for selectively projecting light affected or not affected by the liquid crystal display. The liquid crystal display, for example, selectively transmits light and at least one of scatters and absorbs light, and the optical device includes a projection lens for projecting light to form an image that is a function of selective operation of said liquid crystal display and a selecting device, such as a mask or aperture, for selecting the light from the liquid crystal display for projection to form such image. A method for projecting an image also is disclosed and includes directing incident light to a liquid crystal device capable of affecting or not affecting such incident light, and selectively projecting light affected or not affected by such liquid crystal device to form an image. The projected light may be colored, for example using a selectively operable liquid crystal filter and/or a liquid crystal display that colors light incident thereon.
