Abstract
A flat panel display device is composed of a display section and an electron gun section which provides electron beams for forming a visual display on the display section. A line cathode within the electron gun section serves as the electron source. A plurality of electrode pairs are voltage biased to establish the conditions under which electrons are ejected from the cathode and also to focus electron beams for propagation along the display section.
