Abstract: PROBLEM TO BE SOLVED: To enhance the convergency of an electron beam in an electron emission element which is formed by stacking a cathode electrode, an insulating layer, and a gate electrode, and in which a through hole is formed by removing a part of the gate electrode so as to expose the cathode electrode. SOLUTION: In the electron emission element which is formed by stacking the cathode electrode, the insulating layer, and the gate electrode, and in which the through hole is formed by removing a part of the gate electrode so as to expose the cathode electrode, only the vicinity of the center of an electron emission layer on the cathode electrode is connected to the cathode electrode. Electron beams are therefore generated only in the vicinity of the center of the electron emission layer connected to the cathode electrode, the electron emission element with a small beam diameter and an image forming device forming a fine image are provided.

Abstract: PROBLEM TO BE SOLVED: To provide an electron emission element, a driving method thereof, an electron source, and an image forming device, where driving can easily and stably be controlled at a low voltage. SOLUTION: An anode electrode 6 is applied with a drive voltage (for example, 10 kV). When driving, a gate electrode 4 is applied with, for example, 0 V so that the intensity of an electric field acting on a cathode electrode 2 is higher than a threshold electric field when the cathode electrode starts emission of electrons. When not driving, the gate electrode 4 is applied with a control voltage (for example, -15 V) so that the intensity of electric field acting on the cathode electrode 2 is lower than the threshold electric field.

Abstract: PROBLEM TO BE SOLVED: To enhance electron emitting efficiency and converge an electron orbit at the same time. SOLUTION: In this electron emitting device, an electron emitting element is generally laminated with a low potential side electrode 2, an insulating layer 3 and a high potential side electrode 4 on a substrate 1 and the high potential side electrode 4 is sandwiched by the low potential side electrode 2 from both sides through the insulating layer 3. On the side surface of the high potential side electrode 4 and the insulating layer 3, conductive films 7A and 7B that are connected to the high potential side electrode 4 and the low potential side electrode 2, respectively, are formed opposedly thereto with a space 6 interposed. An anode electrode is opposedly disposed above the substrate 1. When a voltage Vf is applied between the low potential side electrode 2 and the high potential side electrode 4, a voltage Va is applied between the low potential side electrode 2 and the anode electrode, where the distance between the element and the anode electrode is H; Xs=H*Vf/(π*Va), a width W of the high potential side electrode 4 is 0.5 to 15-fold of Xs, inclusive.
