Abstract
A field emission device includes: a first substrate on which a gate electrode line, a cathode line, and an electron emission source are formed; a second substrate disposed to face the first substrate, and on which an anode and a phosphor layer are formed; and a side frame surrounding an area between the first substrate and the second substrate, and forming a sealed internal space, wherein the first substrate and the second substrate respectively comprise a first protrusion part and a second protrusion part that protrude outside the side frame in the same direction, wherein a rear terminal part for applying a voltage to the gate electrode line and the cathode line is formed on the first protrusion part, wherein an anode terminal for applying a voltage to the anode is formed on the second protrusion part.
