Abstract
An electron-emitting device has at least a cathode electrode, an electron-emitting member which is electrically connected to the cathode electrode, and a resistive layer which is provided between the cathode electrode and the electron-emitting member. The resistive layer is composed of the same material as that of the electron-emitting member, and film density of the resistive layer is lower than film density of the electron-emitting member.
