Abstract: A field emission device comprising a first substrate, a second substrate spaced apart from the first substrate, a first metal layer on the first substrate, the first metal layer including a number of first metal lines, a second metal layer over the first metal layer, the second metal layer including a number of second metal lines, emitters over the first metal layer, the emitters being configured to emit electrons toward the second substrate, a luminescent layer between the first substrate and the second substrate, the luminescent layer being configured to provide light when the electrons impinge thereon, and a third metal layer between the second substrate and the luminescent layer, the third metal layer being configured to reflect the light from the luminescent layer toward the first substrate, wherein the first metal lines are substantially parallel to the second metal lines.

Abstract: A method for fabricating an anode plate of field emission luminescent device is provided. The method includes the steps of forming a metal layer on a substrate by using the physical or chemical deposition, printing a pattered protection layer on the metal layer, and sintering the pattered protection layer and oxidizing a potion of the metal layer, which is not covered by the pattered protection layer, so as to form a pattered electrode on the metal layer.

Abstract: A novel electrode pattern design for the electrode plate of field emission device is provided. The electrode plate includes an active region having thereon an electrode layer and a non-active region having thereon a dummy structure or dummy electrode. The material of the dummy electrode is selected from one of the electrode layer materials or the material of the dummy electrode has a coefficient of thermal expansion approximately approaching what the electrode layer material has, so that the stress concentration effect occurring in the non-active region can be eliminated.

Abstract: A reflection-type field emission luminescent device is provided. The field emission luminescent device includes a cathode plate having an electron-emitting source formed thereon for emitting an electron beam, an anode plate including a first side having thereon an anode electrode layer and a fluorescence layer and a second side having thereon a reflection layer, and a vacuum formation structure formed between the cathode plate and the anode plate, in which the electron-emitting source, the anode electrode layer and the fluorescence layer are arranged.
