摘要：
An electron-emitting device of the present invention has an electron-emitting film, and the electron-emitting film is composed of a first layer made of a first material, and a plurality of particles made of a second material whose electric resistivity is lower than that of the first material and provided into the first layer. The first material contains oxygen and nitrogen. A method for manufacturing the electron-emitting device according to the present invention has a step of forming the electron-emitting film, and the electron-emitting film forming step includes a step of forming the plurality of particles made of a second material whose electric resistivity is lower than that of a first material into the first layer made of the first material containing oxygen and nitrogen.
