摘要：To provide an electron-emitting device that can be used to manufacture animage forming apparatus having a superior display quality and in which the developmentof the abnormal light emission point is suppressed and the unevenness of brightness is
not caused. The electron-emitting device includes: a cathode electrode and a gateelectrode, which are formed on a base surface and opposed to each other with a spacetherebetween; and an electron-emitting film which is located on the cathode electrode,and in the electron-emitting device, the electron-emitting film has two end portions (Aand B) in a plane substantially parallel to the base surface in a direction substantiallyperpendicular to a direction along which the cathode electrode and the gate electrodeare opposed to each other, and a structure is used in which electric field strengthsapplied between each of the two end portions (A and B) of the electron-emitting film andthe gate electrode are made weaker than an electric field strength applied between aregion between the two end portions (A and B) of the electron-emitting film and the gateelectrode at a time of driving.
