摘要:
An electron beam emitting device having a first plate provided with electron emitting elements (15) and an electrode (8) opposed to the first plate and given a potential for accelerating electrons emitted from the electron emitting elements (15). A potential regulating part (9) is provided on the electrode (8) side of the first plate, a first potential regulating part that constitutes the potential regulating part (9) is provided within the region of the potential regulating part (9) to which the electrode (8) is projected. The potential regulating part is further defined in a range of 0.83d from the end of the projection region in any direction parallel to the first plate, where d is the distance between the electrode (8) and the potential regulating section (9). Thereby, the path of electrons is stabilized, and a good image can be formed without displacement of light-emission position.
