Abstract: A color display device includes a substrate which forms a partition wall for defining a vacuum space, a plurality of cathode protrusions effecting field emission are formed on the substrate, and a transparent insulator which forms the vacuum space along with the substrate. A plurality of phosphor dots are formed on the surface of the transparent insulator on the side of the vacuum space, are arranged in opposition to the electron sources and have mutually different colors of light emission. Anodes are arranged between the electron sources and the phosphor dots which cause electrons to be generated from the electron sources by field emission, and a transparent electrode is disposed between the phosphor dots and the transparent insulator. Apertures are provided in the anodes through which the electrons pass, whereby the electrons are released from the cathode projections by selectively applying voltages to the anodes, so as to impinge on the phosphor dots of desired color.
