Field emission display with electron emission member and alignment member

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;
• and
• wherein the electron emission member is aligned by the alignment member such that the longitudinal dimension of the electron emission member is substantially vertically extended from the cathode toward the phosphor screen of the anode.
