摘要:
An electron emission light-emitting device comprises an electron emission device and a fluorescent material layer formed on the thin-film metal. The electron emission device comprises an electron-supply layer made of semiconductor formed on an ohmic electrode; an insulator layer formed on the electron-supply layer; and a thin-film metal electrode formed on the insulator layer. The electron emission light-emitting device emits light when an electric field is applied between the electron-supply layer and the thin-film metal.

An electron-emitting device includes an electron source layer made of a metal, a metal alloy or a semiconductor, an insulating layer formed on the electron source layer and a metal thin film electrode formed on the insulating layer. Electrons are emitted upon application of an electric field between the electron source layer and the metal thin film electrode. The insulating layer has at least one island region which constitutes an electron-emitting section in which the film thickness of the insulating layer is gradually reduced. The electron-emitting device further includes a carbon region made of carbon or a carbon compound on at least one of a top, bottom and inside of the island region.

An image display device includes at least one transmissive display panel arranged at different depth positions in a direction normal to a display surface of the image display device. Each of the transmissive display panels includes a light-emitting layer that is sandwiched between a front side transmissive film and a rear side transmissive film. The rear side transmissive film has an interface with a maximum refractive index difference that causes an efficiency of light emitted from the light-emitting layer to become smaller than a front side light emission efficiency in the characteristics of light-emission efficiency, which changes with respect to a film thickness of the transmissive film due to optical interference.

A stereoscopic image display apparatus includes at least two linear image display devices which respectively display linear images in response to image signals. The two linear image display devices are periodically moved by a mechanical scan mechanism along a plurality of locus planes substantially parallel to each other. The mechanical scan mechanism may have a configuration which belt-drives the at least two linear image display devices fixed to a belt, or a configuration which rotationally drives the at least two linear image display devices provided on a disc. The stereoscopic image display apparatus can display a bright and extremely clear stereoscopic image without using a complicated optical system and a light transmissible display panel.
