The electron tube has disposed in an evacuated envelope thereof a plurality of cathode means, each one thereof adapted to emit electrons in response to a control signal. A plurality of sets of at least one cathodoluminescent stripe is disposed within the envelope. Each one of said sets is associated with a corresponding one of the cathode means and adapted to emit light with a predetermined one of a set of primary colors in response to electrons emitted by the corresponding cathode means striking such stripe. An anode for collecting electrons emitted by said cathode is also disposed within the evacuated envelope.
