Patent ID: 6878027

Claim:
A method for producing an electron source comprised of plural electron emission devices, each of which has a gap and is provided with a deposit containing carbon at the gap, said plural electron emission devices connected in a matrix by plural row wirings and plural column wirings, the method comprising: a connecting step of connecting plural pre-elements that are precursors to the plural electron emission devices, to said plural row wirings, respectively; and a voltage applying step comprising plural sub-steps, each of which includes selecting simultaneously certain plural row wirings including plural row wirings that are not adjacent to each other and applying a voltage to the certain plural row wirings selected simultaneously, within an atmosphere containing an organic gas, wherein the sub-steps are conducted successively so that, in each sub-step, the row wirings to which the voltage is applied simultaneously include plural row wirings each of which is adjacent to row wirings to which the voltage was not applied in an immediately prior one of the sub-steps and therefore is not immediately sandwiched by row wirings to which the voltage was applied in the immediately prior one of the sub-steps, wherein at least one deposit is deposited as a result of the voltage applying step.
