PHOSPHOR LIGHT-EMITTING DEVICE, ITS MANUFACTURING METHOD, AND IMAGE FORMER

WIPO Patent Application WO/2004/003961

A1

A phosphor light-emitting device (11) comprises a cold-cathode emitter section (12) for electron emission, a phosphor layer (6) which emits light by collision of electrons emitted from the emitter section (12), an anode section (13) so disposed as to face the emitter section (12) and having an anode (7) and the phosphor layer (6) provided inside the anode electrode (7). This light-emitting device (11) is provided with a porous material layer (5) which is a solid having a solid frame section formed into a three-dimensional network and voids continuous in meshes of the solid frame and is disposed between the emitter section (12) and the anode section (13). The porous material layer (5) transmits electrons emitted from the emitter section (12) through voids and functions as a solid, so that a strength-holding housing is dispensed with while holding the function of emitting light from the phosphor layer (6).
