A liquid crystal display including a light source unit and a liquid crystal panel unit. The liquid crystal panel unit includes picture elements corresponding to three primary colors. The liquid crystal display includes a three-direction unit for receiving light from the light source unit, and emitting rays of the three primary colors having three respective mutually different propagation directions; a first lens group unit, disposed before the picture elements of the liquid crystal panel unit, for receiving the rays of the three primary colors from the three-direction unit, and directing rays of the three primary colors into respective ones of the picture elements corresponding to the three primary colors of the liquid crystal panel unit; and a second lens group unit, disposed after the first lens group unit and having a focal plane disposed outside the liquid crystal panel unit, for receiving rays of the three primary colors having three respective mutually different propagation directions from one of (1) the first lens group unit and (2) the picture elements of the liquid crystal panel unit, and emitting rays of the three primary colors having three respective propagation directions substantially coinciding with one another.
