Zusammenfassung:−8 2An image display apparatus includes a rear plate provided with a plurality of electron-emitting devices, each electron-emitting device emitting electron; a face plate disposed opposite the plurality of electron-emitting devices and provided with a plurality of pixels of phosphor, each pixel of phosphor being irradiated with electrons emitted from corresponding ones of the electron-emitting devices to generate light; and a driver for scanning the plurality of electron-emitting devices for emitting electron from the plurality of electron-emitting devices. The phosphor has luminescence center of allowed transition type material, and the driver scans the plurality of electron-emitting devices so that maximum of charge density dosed in one pixel phosphor, during one scanning period, is equal to or larger than 3×10C/cm.
