    摘要： An electron emitting element of the present invention includes an electron acceleration layer provided between an electrode substrate and a thin-film electrode, which electron acceleration layer includes (a) conductive fine particles and (b) insulating fine particles having an average particle diameter greater than that of the conductive fine particles. The electron emitting element satisfies the following relational expression: 0.3x+3.9≦y≦75, where x (nm) is an average particle diameter of the insulating fine particles, and y (nm) is a thickness of the thin-film electrode 3. Such a configuration allows modification of the thickness of the thin-film electrode with respect to the size of the insulating particles, thereby ensuring electrical conduction and allowing sufficient current to flow inside the element. As a result, stable emission of ballistic electrons from the thin-film electrode is possible.

    摘要： A light emitting element of the present invention includes an electrode substrate; a thin-film electrode; and an electron acceleration layer sandwiched between the electrode substrate and the thin-film electrode. In the electron acceleration layer, as a result of a voltage applied between the electrode substrate and the thin-film electrode, electrons are accelerated so as to be turned into hot electrons. The hot electrons excite surfaces of the silicon fine particles contained in the electron acceleration layer so that the surfaces of the silicon fine particles emit light. Such a light emitting element of the present invention is a novel light emitting element, which has not been achieved by the conventional techniques. That is, the light emitting element of the present invention is able to (i) be produced by using a silicon material, which is available at low price, through a simple production method, and (ii) efficiently emit light.
