Abstract
A field emission device includes a substrate, a first conductive layer formed over the substrate biased at a first voltage level, a second conductive layer formed over the substrate biased at a second voltage level different from the first voltage level, emitters formed on the first conductive layer and the second conductive layer for transmitting electrons, and a phosphor layer formed over the substrate and being disposed between the first conductive layer and the second conductive layer, wherein the electrons are transmitted from one of the first conductive layer and the second conductive layer through the phosphor layer to the other of the first conductive layer and the second conductive layer in a direction substantially orthogonal to the normal direction of the substrate.
