Abstract:
A display device comprising:a rear panel having a plurality of cathode wires having electron emitting sources, a plurality of control electrodes which cross the cathode wires and control an emission quantity of electrons from the electron emitting sources in response to the potential difference between the cathode wires and the control electrodes and a rear substrate, and a face panel having anodes and fluorescent materials, wherein the control electrodes are formed of plate-like members, the control electrodes have holes which allow the electrons emitted from the electron emitting sources to pass therethrough toward the face panel side in first regions which cross the cathode wires, and assuming a distance from the rear substrate to the holes of the control electrodes as â€œaâ€  and a distance from the rear substrate to the control electrodes as â€œbâ€ , the control electrodes have second regions where a relationship a>b is established between the neighboring cathode wires.
