    摘要: An electron emission device for attracting electrons emitted from an electron emission element to an anode, includes a current detector for detecting a flow-in current to said electron emission element and a flow-out current from the electron emission element. The difference between the flow-in current and the flow-out current is calculated and the voltage applied to the electron emission element is adjusted in accordance with the difference between the flow-in current and the flow-out cuttent.

    摘要: A cold cathode device wherein a cold cathode and an anode face each other with an electron transit path intermediated therebetween, and one or more control electrodes structurally insulated from the said cathode and the anode, are provided exposing to the electron transit path. A cold cathode vacuum tube has an electron emission element having a p-type semiconductor region on an electron emission side and a work function lowering region with junctional relation to the p-type semiconductor region; and a plate electrode structurally insulated from the electron emission element by using an insulation layer which is formed with an electron transmit path corresponding in position to an electron emission area of the electron emission element.
