Image display apparatus and method of driving the same

An image display apparatus includes a rear plate provided with a plurality of electron-emitting devices, each electron-emitting devices 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 one of the electron-emitting devices to generate a light; a driver for scanning the plurality of electron-emitting devices for emitting electron from the plurality of electron-emitting devices, wherein the phosphor has luminescence center of allowed transition type material, and said driver scans the plurality of electron-emitting device so that maximum of charge density dosed in one pixel phosphor, during one scanning period, is equal to or lager than 3 × 10 -8 C/cm 2 .
