Abstract
An electron-emitting device has an insulating layer having a side surface, a recess portion formed on the side surface of the insulating layer, a gate electrode which is arranged above the recess portion, and a wedge-shaped emitter which is arranged on an edge of a lower side of the recess portion and has a first slope on a side of the recess portion and a second slope on a side opposite to the recess portion. A lower end of the first slope of the emitter enters the recess portion, and both the first slope and the second slope of the emitter tilt to an outside of the recess portion.
