On the inner surface of the front wall is a cathodoluminescent screen having stripes of different color light emitting phosphor material. Within the envelope and adjacent to the back wall are a plurality of electron beam guides extending in one dimension. The electron beam guides include means for deflecting the beam out of the guide toward the screen. Between the screen and the beam guides in the evacuated envelope is means for focusing the deflected electron beam sequentially onto one of several stripes of the screen.
