PURPOSE: A manufacturing method of a field emission display device is provided to decrease the cost of a driving circuit, etc. by reducing the number of lead lines for connecting negative electrode outside and increasing a fixing space. CONSTITUTION: The manufacturing method of a field emission display device comprises the processes of: forming a gate insulating film(13), a gate metal(15) and an allotted insulating film(17) on the upper part of a cathode metal(11); forming a groove by partly etching the allotted insulating film; forming metal for allotted electrode use on the upper entire surface; forming the allotted electrode by anisotropically etching the metal for allotted electrode use; etching the allotted insulating film of the lower allotted electrode; and forming a gate hole bi etching the gate metal and the gate insulating film, and forming an emitter tip inside.
