Abstract
An electron emitting element of the present invention includes an electron acceleration layer sandwiched between an electrode substrate and a thin-film electrode, and the electron acceleration layer includes a fine particle layer containing insulating fine particles and a basic dispersant. This makes it possible to provide an electron emitting element which does not cause insulation breakdown in an insulating layer and which can be produced at a low cost.
