Patent ID: 8169134

Claim:
A field emission device comprising: a first substrate which comprises a first protrusion, and on which a at least one gate electrode line, at least one cathode line, and at least one electron emission source are formed; a second substrate which comprises a second protrusion part, and on which an anode and a phosphor layer are formed; a side frame which is interposed between the first substrate and the second substrate and surrounds an area between the first substrate and the second substrate to form a sealed internal space, wherein the first protrusion part of the first substrate and the second protrusion part of the second substrate protrude outside an outer periphery of the side frame in a first direction; a rear terminal part through which a voltage is applied to the gate electrode line and the cathode line, and which is formed on the first protrusion part; and an anode terminal through which a voltage is applied to the anode, and which is formed on the second protrusion part.
