ABSTRACT:
A technique for correcting an electron trajectory and preventing positional deviation of a light emitting point in an image display apparatus is disclosed. The image display apparatus includes a rear plate which is provided with an electron source having electron-emitting devices, a plurality of wiring electrodes for supplying a drive signal to the electron-emitting devices, a face plate disposed to be opposed to the rear plate and a spacer which is arranged between the face plate and the rear plate and is provided with a spacer electrode on a contact surface which is in contact with the rear plate. And, this image display apparatus is unique in that a distance L1between a first wiring electrode and a center of a first electron-emitting region and a distance L2between a second wiring electrode and a center of a second electron-emitting region satisfy a relationship L1>L2.
