A high resolution, cathodoluminescent display screen or device and a method of producing such a display device is disclosed. The display screen includes a plurality of channel structures having longitudinal ends, a transparent medium formed in a plane to which the channel structures are fixed with one longitudinal end thereof oriented toward the plane of the transparent medium, and a cathodoluminescent material deposited on the channel structures whereby incident electrons and light generated by the incident electrons are directed along the channel structures. Preferably, the display screen also includes a mechanism for removing built up charge from the display screen, such as conductive channel structures and/or a conductive transparent medium. The cathodoluminescent material can include phosphors, and for producing a color display, different materials producing different colors would be used. In one preferred embodiment, the channel structures are tubules. Alternately, the channel structures can be channel plates or other structures providing channeling structures. In the preferred embodiment, the transparent medium is glass. However, the transparent medium could be quartz or some other equivalent material. In order to provide a display device the display screen is then mated with an addressable electron source for generating electrons incident on the cathodoluminescent material of selected channel structures. Preferably, the electron source means includes a field emitter array with a reflecting surface.
