Patent ID: 7097530

Claim:
An electron source substrate comprising: a plurality of row-directional wirings laid in a row direction; a plurality of column-directional wirings, each respectively having a wiring resistance higher than that of a row-directional wiring corresponding thereto, and laid in a column direction so as to intersect with that row-directional wiring; and a plurality of electron-emitting devices, wherein one end of each of the electron-emitting devices is electrically coupled to a corresponding row-directional wiring, a further end of each of the electron-emitting devices is electrically coupled to a corresponding column-directional wiring, and a predetermined drive voltage is supplied through said row-directional wirings and column-directional wirings to each of the electron-emitting devices, wherein electrical coupling between the further end of each of the electron-emitting devices and the corresponding column-directional wiring is formed through a first resistor element, and a resistance value of the first resistor element is larger than the wiring resistance of the column directional wirings.
