PCT No. PCT/RU93/00305 Sec. 371 Date Jul. 18, 1995 Sec. 102(e) Date Jul. 18, 1995 PCT Filed Dec. 15, 1993 PCT Pub. No. WO94/17546 PCT Pub. Date Aug. 4, 1994An edge emitter display device is provided comprising an anode (1) and a cathode (2). Cathode (2) is situated at a level above and laterally displaced from anode (1), providing an opening for a window above anode (1). Cathode (2) has an emitting edge (4) which is operable to emit field electrons when a positive voltage is applied to anode (1) with respect to cathode (2). A phosphor layer is disposed above anode (1) and below the level of cathode (2) and is operable to luminesce when struck with the electrons emitted from the emitting edge (4).
