To provide an electron emission element preventing static charge from being stored on a surface of an insulating layer without increasing the number of components.

By providing: cathode electrodes 6 being first electrodes formed on a substrate in a predetermined pattern; gate electrodes 10 being second electrodes crossing the cathode electrodes 6 on their upper parts and formed into a predetermined pattern; the insulating layer 8 formed between the cathode electrodes 6 and the gate electrodes 10; and a plurality of conductive layers 22 separated from the gate electrodes 10, partially covering a surface of the insulating layer 8 and electrically connected to the cathode electrodes 6, the conductive layers 22 covering the insulating layer 8 in non-display areas and controlled simultaneously with the cathode electrodes 6 can prevent static charge from being stored on the surface of the insulating layer 8.
