    Abstract: A vacuum fluorescent display includes a cathode electrode, grid electrode, anode electrode, at least one envelope, phosphor screen, and cap. The cathode electrode emits electrons. The grid electrode extracts the electrons from the cathode electrode. The anode electrode accelerates the electrons extracted from the cathode electrode. The envelope accommodates the cathode electrode, grid electrode, and anode electrode in a vacuum space and has a phosphor screen plate having light transmission properties. The phosphor screen is formed on an inner surface of the phosphor screen plate of the envelope and adapted to emit light upon bombardment of the electrons accelerated by the anode electrode. The cap is made of an X-ray shielding material and supported outside the envelope so as to surround the phosphor screen plate of the envelope through a gap. The cap has a light exit portion from which the light emitted from the phosphor screen emerges through the phosphor screen plate of the envelope.

    Abstract: A field emission cathode (40) includes field emitting bodies (42) in the form of fibers, and a base body having a longitudinally extending core (41) formed by at least two wires (43) between which the fibers are secured. The fibers are distributed along at least a part of the length of the core (41) and extend radially outwards from the core. A light source (10) includes an evacuated container having walls at least a portion of which consists of an outer glass layer (23) on which at least a major part thereof is coated on the inside with a layer of phosphor (24) forming a luminescent layer, and a conductive layer forming an anode (25). The layer of phosphor (24) is excited to luminescence by electron bombardment from a field emission cathode (40) located in the interior of the container, and a modulator electrode or grid (30) is arranged between the cathode (40) and the anode (25) for creating an electric field for the emission of electrons. The field emission cathode (40) includes field emitting bodies (42) in the form of fibers, and a base body having a longitudinally extending core (41) formed by at least two wires (43) between which the fibers are secured.
