ABSTRACT:
A flat type display device capable of being substantially thinned and carrying out display of very high definition on a large image plane. A plurality of electron streams emitted from a cathode arranged at one end of a airtight casing in a manner to be deviated from a phosphor screen section are guided and turned toward the phosphor screen section. Then, the electron streams are selected and controlled by an address electrode section, resulting in formation of an electron beam, which is then accelerated by an accelerating electrode section and impinged on the phosphor screen section for desired luminous display.
