Image display apparatus and manufacturing method thereof

An image display apparatus comprising:

• a face plate with a plurality of light-emitting regions;
• a rear plate with electron-emitting devices corresponding to the plurality of light-emitting regions, respectively;
• and
• a drive circuit that drives the electron-emitting devices,
• wherein the drive circuit has a correction circuit that calculates a correction value evaluated by influence of emitted electrons from proximate electron-emitting devices which correspond to light-emitting regions around the light-emitting region to be corrected, and corrects a signal input to the electron-emitting device corresponding to the light-emitting region to be corrected based on the correction value, and
• the correction circuit has an adjustment circuit that adjusts the correction value based on variation of electron-emitting characteristics of the proximate electron-emitting devices.
