ELECTRON EMITTING DEVICE AND IMAGE FORMING APPARATUS USING DEVICE THEREIN

摘要

PURPOSE:To provide electron emitting devices which have self-promoting property to correct defects of electron emitting parts without being given any structural alteration from outside and have little fluctuation of properties among the devices. CONSTITUTION:An electron emitting device has a characteristic wherein a plurality of electron emitting parts 5 electrically connected in series between a pair of electrodes 1, 2 and single electron emitting part 5 are arranged electrically in parallel rows one another and the total number of the electron emitting parts for each row arranged in parallel is different from that of another row.
