A method of producing a substrate for an electron source, the substrate including a plurality of electron emission devices each including a pair of opposing electrodes, the plurality of electron emission devices being arranged on the substrate. The method comprises the steps of preparing an intaglio plate having recessed portions corresponding to a pattern of the electrodes, the depth of the recessed portions being in the range from 4 .mu.m to 15 .mu.m, filling the recessed portions with ink, pressing a blanket against the intaglio plate so that the ink is transferred from the inside of the recessed portions onto the blanket, and bringing the blanket into contact with the substrate so that the ink is transferred from the blanket onto the substrate thereby forming the electrode pattern thereon.
