摘要:
An electron emission device exhibits a high electron emission efficiency. The device includes an electron-supply layer of metal or semiconductor, an insulator layer formed on the electron-supply layer, and a thin-film metal electrode formed on the insulator layer. The insulator layer has a film thickness of 50 nm or greater. The electron-supply layer has a silicide layer. When an electric field is applied between the electron-supply layer and the thin-film metal electrode, the electron emission device emits electrons.

An electron emission device exhibits a high electron emission efficiency. The device includes an electron-supply layer of metal or semiconductor, an insulator layer formed on the electron-supply layer, and a thin-film metal electrode formed on the insulator layer. The insulator layer has at a film thickness of 50 nm or greater and a field-stabilizing layer. When an electric field is applied between the electron-supply layer and the thin-film metal electrode, the electron emission device emits electrons.

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 display apparatus (1) for generating a stereoscopic image by superimposing a plurality of images at a predetermined interval from each other on the view line of the viewer, the apparatus comprising: a first display unit (11) having a plurality of emission areas (11-1) for emitting a light, disposed in a discrete manner in a plane of a display screen and a plurality of transmission areas (11-2) for transmitting a light, disposed in a discrete manner in the plane of the display screen except for areas occupied by said plurality of emission areas; and a second display unit (12) disposed behind the first display unit as seen from the viewer.
摘要:
A three-dimensional image display device including at least one transmissive light-emitting display panel and a second light-emitting display panel located behind the transmissive panel. The transmissive panel has a plurality of light-emitting portions arranged in two dimensions and classified into plural linear groups. The transmissive panel has a plurality of bus lines each of which is connected to and overlapping with the light-emitting portions in per group. Each light-emitting portion includes a light-emitting layer made of an organic compound exhibiting electroluminescence. Each overlapped portion of the bus line has an area equal to or smaller than 5% of an area of each of the light-emitting portions.

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.
