Abstract
In order to suppress variation in delivery amounts in dispensing a material for forming electron emitting portions, a substantially homogeneous material is dispensed from a plurality of output portions to each of plural objective portions. This averages amounts of the material dispensed to the respective objective portions even if there is variation in delivery amounts of material from the respective output portions.
