Patent ID: 6851995

Claim:
A method of manufacturing an electron source including a plurality of row wirings, a plurality of column wirings, and a plurality of electron emitting devices each connected therewith, which are provided on a substrate, the method comprising: a forming step of forming an electron emitting portion in each of the electron emitting devices; and an activation step of applying a voltage to the electron emitting devices in an activation gas atmosphere to deposit one of carbon and a carbon compound on a region including the electron emitting portion, wherein the activation step has a compensation voltage applying step of selecting part of either one of the row wirings and the column wirings, and determining a potential of a selected wiring so that, when the voltage is applied to all the electron emitting devices connected with the selected wiring, a compensation voltage for compensating for a voltage drop caused in the selected wiring is applied to the electron emitting devices connected with the selected wiring through another of the row wirings and the column wirings, wherein the activation step includes a first activation step, a second activation step that is conducted after the first activation step, and a predetermined time interval separates the first and second activation steps, and wherein in the compensation voltage applying step, an operation for limiting the compensation voltage applied to the electron emitting devices connected with the selected wiring for a predetermined period from the beginning of the second activation step is conducted.
