Title:
電界放出素子及びこれを用いた電界放出表示装置
Document Type and Number:
Japanese Patent JP2007511881
Kind Code:
A
Abstract:
Provided are a field emission device and a field emission display device using the same. The field emission device includes a cathode portion having a substrate, a cathode electrode formed on the substrate, and a field emitter connected to the cathode electrode; a field emission-suppressing gate portion formed on the cathode portion around the field emitter and surrounding the field emitter; and a field emission-inducing gate portion having a metal mesh with at least one penetrating hole, and a dielectric layer formed on at least a part of the metal mesh, wherein the field emission-suppressing gate portion suppresses electrons from being emitted from the field emitter, and the field emission-inducing gate portion induces electrons to be emitted from the field emitter. According to this configuration, the conventional problems of the field emission device including a gate leakage current, electron emission caused by an anode voltage, electron beam divergence can be significantly improved.
