Abstract:
A field emission display comprising:first and second substrates spaced apart from each other with a predetermined distance, the first substrate having a top surface and the second substrate having a bottom surface, the top surface of the first substrate facing the bottom surface of the second substrate; a cathode disposed on the top surface of the first substrate, the cathode having a top surface and a bottom surface, the bottom surface of the cathode contacting the top surface of the first substrate; an anode disposed on the bottom surface of the second substrate, the anode having a top surface and a bottom surface, the top surface of the anode contacting the bottom surface of the second substrate; a phosphor screen formed on the bottom surface of the anode; and an emitter formed on the top surface of the cathode, the emitter facing the phosphor screen; wherein the emitter comprises an electron emission member having a longitudinal dimension and an aspect ratio greater than one and an alignment member for aligning the electron emission member relative to the cathode; wherein the alignment member is formed with a magnetic material.
