Field emission flat lamp and fabricating method thereof, and cathode plate and fabricating method thereof

A field emission flat lamp, comprising:

• a cathode plate, including:
• a first substrate;
• a plurality of cathode structures, disposed on the first substrate, wherein the cathode structures are in a strip-form and are arranged parallel to one another, and each of the cathode structures has at least one groove;
• a plurality of gate structures, disposed on the first substrate, wherein the gate structures are in strip-form, and the gate structures and the cathode structures are parallel interlaced with one another;
• an emission layer, disposed in the grooves;
• an anode plate, disposed above the cathode plate;
• and
• a sealant, disposed and sealing between the anode plate and the cathode plate.
