Abstract: A light emitting display element comprising an antiferroelectric layer (2), top- and back-face electrodes (3 and 4) for impressing an alternating electric field upon the layer (2), and a phosphor layer (6) which emits light on receiving cold electrons emitted from the layer (2) when the alternating electric fields are impressed upon the layer (2). The top- and back-face electrodes (3 and 4) are respectively provided on the top and back surfaces of the layer (2) and at least either of the electrodes (3 and 4) can be comb-shaped or perforated. A flat display (20) is constituted by arranging such light emitting display elements (1) on a plane. The flat display (20) has a large display area in spite of its light weight and small size and exhibits excellent display characteristics stably for a long term.

Abstract: A field emitter includes a cathode, a field emission point part, a first anode, a charge storing plate, and a second anode. The field emission point part faces the first anode and is disposed at a first surface of and electrically connected to the cathode. The charge storing plate is disposed at a second surface, opposite the first surface, of the cathode. The second anode faces the second surface of the cathode. The charge storing plate is interposed between the second anode and the second surface of the cathode. Even if substantially the same electric field is formed in the field emitter as in a field emitter without the charge storing plate, the field emitter having the charge storing plate induces a more effective field emission current than the field emitter without the charge storing plate.
