Abstract
An image display apparatus of smaller beam deviation is provided by making smaller the absolute value of an angle formed by an initial velocity vector of an electron emitted from the first electron-emitting devices closest to a spacer 100 and a line parallel to the longitudinal direction of a spacer 100, rather than the absolute value of an angle formed by an initial velocity vector of an electron emitted from the second electron-emitting devices secondary closer to the spacer 100 and the line parallel to the longitudinal direction of the spacer 100.
Claims3
An image display apparatus comprising:
- a rear plate including thereon first and second electron-emitting devices each having a pair of device electrodes disposed in opposition to each other sandwiching a gap therebetween, and an electron-emitting region between the pair of device electrodes;
- a face plate having a phosphor;
- and
- a plate shaped spacer disposed between the rear plate and the face plate, closer to the first electron-emitting device rather than the second electron-emitting device, wherein
- a longitudinal direction of the gap of the first electron-emitting device is inclined at a first inclination angle to a direction perpendicular to a longitudinal direction of the spacer, a longitudinal direction of the gap of the second electron-emitting device is inclined at a second inclination angle to the direction perpendicular to the longitudinal direction of the spacer, and the second inclination angle is larger than the first inclination angle.
