Patent ID: 7733005

Claim:
A light emission device comprising: first and second substrates opposing each other; a plurality of cathode electrodes that are arranged on the first substrate and spaced apart from each other; a gate electrode that is electrically insulated from the cathode electrodes; an insulation layer formed between the gate electrode and the cathode electrodes, wherein the insulation layer comprises first and second opposing surfaces which are directed to the first and second substrates, respectively, and wherein a plurality of opening are defined in the gate electrode and the insulation layer; a plurality of electron emitters that are electrically connected to each of the cathode electrodes and located in the openings, respectively, wherein the plurality of electron emitters are configured to emit electrons toward the second substrate, via the plurality of openings, respectively; a phosphor layer that is formed on the second substrate, wherein the emitted electrons are configured to collide the phosphor layer; and an anode electrode that is located on the second substrate, wherein the second substrate is configured to emit light by way of excitation of the phosphor layer, wherein the gate electrode substantially completely covers the second surface of the insulation layer.
