Abstract
An image display apparatus includes at least one electron-emitting device, at least one wiring arranged to apply a voltage to the electron-emitting device, a getter disposed on the wiring, and an insulating layer interposed between the getter and wiring. The getter has penetrating portions formed in a part thereof corresponding to a region where an image is displayed in the image display apparatus. The penetrating portions are at least one opening, and an area of an inner wall surface of the getter facing the opening is substantially the same as or larger than an area of the opening.

An image display apparatus comprising:
- at least one electron-emitting device;
- at least one wiring arranged to apply a voltage to the electron-emitting device;
- and
- a getter disposed on the wiring, and an insulating layer interposed therebetween,
- wherein the getter has penetrating portions formed in a part thereof corresponding to a region in which an image is displayed in the image display apparatus,
- the penetrating portions are at least one opening, and
- an area of an inner wall surface of the getter facing the opening is substantially the same as or larger than an area of the opening.
An image display apparatus comprising:
- at least one electron-emitting device;
- at least one wiring arranged to apply a voltage to the electron-emitting device;
- and
- a getter disposed on the wiring, and an insulating layer interposed therebetween,
- wherein the getter has penetrating portions formed in a part thereof corresponding to a region in which an image is displayed in the image display apparatus,
- the penetrating portions are at least one cut groove, and
- an area of an inner wall surface at the cut groove is substantially the same as or larger than an area of the cut groove.
An image display apparatus comprising:
- at least one electron-emitting device;
- at least one wiring arranged to apply a voltage to the electron-emitting device;
- and
- a getter disposed on the wiring, and an insulating layer interposed therebetween;
- wherein the getter has penetrating portions formed in a part thereof corresponding to a region in which an image is displayed in the image display apparatus, and
- the penetrating portions have shapes that cause the getter to resist deterioration of adsorption performance away from a level obtained in a case where a getter having no penetrating portions is used in the device.
