Abstract
A miss landing measure on a face plate of electrons emitted from electron-emitting devices by the warping of a rear plate and the face plate accompanying heat processes, such as seal bonding, is provided. Initial velocity vectors of electrons emitted from an electron-emitting area of an electron-emitting device formed on the rear plate has a distributed tendency according to an in-plane distribution of normal line directions of the rear plate so that the electrons emitted from each of the plurality of electron-emitting devices may irradiate each of the plurality of light emitting portions, corresponding to each of the electron-emitting devices, formed on the face plate.
