ABSTRACT:
The present invention provide a lateral type electron-emitting device in which abnormal discharge near an electron-emitting region is suppressed, electron emission characteristics are stable, and electron emission efficiency is high. A method of manufacturing an electron-emitting device of the invention includes: a first step of preparing an electron-emitting electrode and a control electrode that are arranged on a surface of an insulating substrate; and a second step of covering the surface of the insulating substrate, which is located between the electron-emitting electrode and the control electrode, with a resistive film to connect the electron-emitting electrode and the control electrode. In the method of manufacturing an electron-emitting device, the resistive film is arranged to cover an end of a surface of the electron-emitting electrode opposed to the control electrode.
