Abstract
Provided is a current controlling device for controlling an electric field emission current in connection with an electric field emission device which emits electrons in response to an applied voltage, the device including: a first current controlling transistor forming a current path in response to a first gate voltage; a second current controlling transistor connected between the field emission device and the first current controlling transistor and forming a current path in response to a second gate voltage; and a control logic controlling the first and second gate voltages, wherein the control logic controls a upper limit of the field emission current by using the first gate voltage.
