Field emission device

A field emission device comprising:

• a first substrate 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 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 substrate is offset from the second substrate by a predetermined length in a first direction perpendicular to a direction in which the first substrate is spaced apart from the second substrate by the side frame;
• a rear terminal part through which a voltage is applied to the gate electrode line and the cathode line, and which is formed on a protruding region of the first substrate protruding by the predetermined length;
• and
• an anode terminal through which a voltage is applied to the anode, and which is formed on at least one corner of the second substrate, corresponding to the protruding region of the first substrate.

A field emission device comprising:

• a first substrate which comprises a first protrusion part;
• a stacked structure which is disposed on the first substrate and comprises at least one gate electrode line, at least one cathode line, and at least one electron emission source;
• a second substrate which comprises a second protrusion part;
• an anode which is disposed on the second substrate;
• a phosphor layer which is disposed on the anode and faces the stacked structure;
• 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 same direction;
• a rear terminal part which disposed on the first protrusion part and connected to the gate electrode line and the cathode line;
• and
• an anode terminal which is disposed on the second protrusion part and is connected to the anode.
