ELECTRON-EMITTING DEVICE AND IMAGE DISPLAY APPARATUS

摘要

An image display apparatus uses electron-emitting devices each having: a pair of device electrodes on an insulating substrate; and an electroconductive film connecting the device electrodes. The insulating substrate has concave portions in a gap between the device electrodes. The film has opening portions having a first gap in a region adjacent to the opening portions along such a gap. A carbon film having a second gap is formed in the first gap and has extending portions extending from side surfaces of the concave portions toward the bottom. The extending portions of the adjacent carbon films are not coupled.
