Abstract
The present invention provides an electron amplification plate placed between a first substrate and a second substrate of a field emission display device. The electron amplification plate comprises at least two insulating layers for electrical insulation; and at least one conductive electrode layer having plural apertures, wherein the conductive electrode layer is sandwiched between the insulating layers. The surface of the inner wall of the apertures is coated with an electron-amplifying material for multiplying the quantity of electrons as the surface is impacted. The inner wall of each aperture comprises an upper concave wall and a lower concave wall, and the lower concave wall is used for collecting electrons, and the upper concave wall is used for focusing electrons. Thereby, the electron beam emitted from the emitters can be effectively amplified, and color purity of the field emission display device is high.
