    Abstract: An electron discharge element includes: a lower electrode (2) near to a substrate and an upper electrode (7) far from the substrate; insulation layers (5, 6) layered between the lower electrode (2) and the upper electrode (7) and an electron supply layer (4). The electron discharge element discharges electrons from the upper electrode (7) when voltage is applied across the lower electrode (2) and the upper electrode (7). The electron discharge element further includes an electron discharge unit (14) having an opening formed by a stepwise inner wall of the insulation layers (5, 6) whose film thickness is stepwise reduced; and a carbon region (8) connected to the upper electrode (7), arranged in contact with the insulation layers (5, 6) and the electron supply layer (4), and containing carbon. Thus, it is possible to create an element having the same electron discharge characteristic as an electron discharge element in which the insulation layer film thickness is gradually reduced, without using minute particles or a micro-mask.

    Abstract: A method for manufacturing an electron emitting device composed of an electron emitting element wherein a lower electrode (11), an electron supplying layer (12), an insulating layer (13) and an upper electrode (15) are successively stacked on a substrate. The method includes a micro mask (MM) forming process wherein a plurality of micro masks are formed on the electron supplying layer. The micro mask is provided with a supporting part (P) protruding in a normal line direction of a substrate, and a main mask part (M) protruding from the supporting part in a direction vertical to a normal line direction of the substrate. An electron emission device having the micro mask remained is also provided. By using the micro mask having the supporting part and the main mask part, the electronic emission element arranged with finely filled arrangement and regularity, which could not have been obtained by methods employing fine particles, and an effective width of a bottom part of the supporting part and an effective width of the main mask can be independently decided. Therefore, the micro mask having higher mask effects and less destruction possibilities compared with methods using a reversely tapered blocks is provided.

    Abstract: An electron emitting device is composed of a plurality of electron emitting elements. The electron emitting element is provided with a lower electrode (11) and an upper electrode (15) and emits an electron from an upper electrode side. In the electron emitting device, a space is formed between the electron emitting elements and the upper electrode extends over the space on a bridge part (15a). The space is formed by providing a through hole or a notched part (15a) on the bridge part, and etching a stacked body under the upper electrode by using the bridge part as a mask. The upper electrodes of the adjacent electron emitting elements are electrically connected by the bridge part without bringing the upper electrodes into contact with the electron emitting element side planes and a substrate. Therefore, a current path can be shortened and a possibility of disconnection can be reduced.
