Abstract:
1. An image display apparatus comprising: a rear plate having a plurality of electron-emitting devices; a face plate having a plurality of pixels, each pixel having one or more phosphors that emit fluorescence in response to electrons emitted from the electron-emitting devices; and a drive circuit configured to drive the electron-emitting devices with line-sequential driving manner, wherein in at least one pixel of the pixels, a first phosphor and a second phosphor are layered on a substrate of the face plate in order of the second phosphor and then the first phosphor, the first phosphor emits fluorescence in response to the electrons emitted from the electron-emitting devices, and the second phosphor emits, in response to the fluorescence emitted from the first phosphor, a visible light by which the pixel forms an image, the first phosphor is a mixed alkaline earth silicate phosphor represented by M the second phosphor is CaAlSiN
