A portable LCD-type projector for images on a viewing surface such as a projection screen. The projector includes a housing having top, bottom, front and back panels hingedly connected in a parallelogram. The housing panels are movable from a first, generally flat folded position to a second, open position in which the top and bottom panels are generally horizontal and the front and back panels are oriented at a generally 45.degree. angle. The projector includes a light source, a lens, and an LCD or similar image-generating panel. The LCD panel is carried in a location optically between the light source and the lens. The LCD panel is movable from a first, generally horizontal stored position to a second, generally vertical operating position. Mirrors are provided for directing light emitted by the light source through the LCD panel and the lens for projection on a projection screen.
