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-plain 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.
Claims6
A display apparatus, comprising:
- an electron source substrate having an electron source including a plurality of electron-emitting devices, each having an electron-emitting area between a pair of electrodes, a plurality of row directional wirings and a plurality of column directional wirings, both of said wirings connecting said plurality of electron-emitting devices;
- and
- a counter substrate located in opposition to the electron source substrate, said counter substrate including a plurality of light emitting portions corresponding to said plurality of electron-emitting devices, wherein
- in said electron source substrate, directions of normal lines of a surface of an electron source forming region are distributed in a tendency, and initial vectors of electrons emitted from said electron-emitting areas of said electron-emitting devices are distributed in a tendency corresponding to the distributed tendency of said normal line direction so that electrons emitted from each of said plurality of electron-emitting devices may irradiate each of said plurality of light emitting portions which corresponds to said electron-emitting device.
