There is provided a single panel type video display capable of increasing the luminance of image. A color separator separates light from a light source into light beams in three colors in a band shape to emit the light beams and introduces the band-shaped light beams in the three colors so as to be overlapped with one another in a predetermined region. A lens array wheel has a plurality of functional units each composed of a convex lens of a size corresponding to the predetermined region, circularly passes the plurality of functional units each composed of the convex lens through the predetermined region, and scrolls the band-shaped light beams in the three colors in a state where they are divided among regions on a single liquid crystal display panel. A video signal is fed to the liquid crystal display panel in synchronization with the movement of the plurality of functional units each composed of the convex lens.
