An image projector, having a light source, an LCD panel into which a light emitted from the light source enters, and a projection lens into which the light emitted from the LCD panel enters. There exists, in an entrance pupil of the projection lens, a range in which light emitted from respective pixels of the LCD panel overlap with each other at least in a horizontal direction. The image projector forms part of an image display.

A display system has a directional reflection screen with a triangularly-shaped mirror sheet as horizontal focusing for observers and stereoscopic image projecting means. The directional reflection screen has a triangularly-shaped mirror sheet with included angles at least some of which are non-right angles. This enables a plurality of observers to simultaneously obtain a stereoscopic view using a binocular parallax without wearing special glasses and without having to position themselves in a very limited number of positions relative to the screen. Vertical diffusion can also be provided by using a lens sheet. The screen can be made concave in the horizontal or vertical directions, or both.

High-grade three-dimensional images can be observed without a bright image of an exit end of an image projector superposed on the three-dimensional images. In a method of reproducing three-dimensional images by a three-dimensional image-reproducing device provided with an image projector and a directional reflective screen for collecting light from the image projector toward a specific position in a horizontal direction and for diffusing the light in a vertical direction, the directional reflective screen and the image projector are positioned with respect to the observer observing the three-dimensional images such that the observer is outside a region traversed by a portion of light rays which enter the directional reflective screen from the image projector, then are reflected by a surface of the directional reflective screen incapable of contributing to the reproduction of the three-dimensional images, and form a mirror image or a conjugate image of the image projector.

A directional reflection screen includes a corrugated mirror sheet constituted by a plurality of mirrors, and a lens sheet for diffusing and reflecting rays of light in the direction of ridge lines of the corrugated mirror sheet. The ridge lines of the corrugated mirror sheet intersect the lens lines of said lens sheet at angles other than 90.degree.. The projection display further includes projection means for projecting an image onto the directional reflection screen.

A watercraft has steering force detection sections. Each steering force detection section includes a pressure receiving section. The pressure receiving sections are spaced from each other and are in the vicinity of a steering shaft. A pressing member is coupled to the steering shaft. The pressing member can press on at least one of the pressure receiving sections when the steering handlebars are rotated to a maximum steering angle. A received pressure detection section detects the pressure applied to the pressure receiving section. The pressure receiving section and the received pressure detection section are coaxially mounted in a pressure receiving section casing and a detection section casing. A guide tube can engage the pressure receiving section and the received pressure detection section. The guide tube is formed with ribs and grooves. The pressure receiving section has a pressure receiving member, a bolt, a plain washer, and a spring member.

On a back surface of a back substrate on which electron emission sources are formed, a getter room is formed by the back substrate and a cup-shaped room member. In the inside of the getter room, a getter assembly which includes a getter housing which holds a getter and a getter support which supports the getter housing is arranged. End portions of the getter support are fixed to and arranged between the back substrate and the room member by a sealing material. The present invention provides an image display device which prevents the occurrence of cracks in the getter room thus suppressing the degradation of a display characteristic of the image display device.

Light-emitting devices and light-emitting displays for realizing bright display by allowing light emitted from an emissive layer to efficiently contribute to a display. Polarization separators are arranged between the emissive layer and a phase plate. In the light of a wavelength range which includes a part or all of a light-emission wavelength range of the emissive layer and is narrower than a visible wavelength range and is directed from the emissive layer side to the polarization separators side, the polarization separators reflect circularly polarized light components which are converted into linearly polarized light that is absorbed by the polarizer due to the operation of the phase plate and transmit the other light.

A display device includes a face substrate which has anodes and phosphors on an inner surface thereof, a back substrate which has cathode lines and electron sources formed on the cathode lines, a support body which is interposed between both substrates such that the support body surrounds a display region and forms a given inner space, and a sealing material which hermetically seals the support body and both substrates. To enable the display device to produce a high quality display and have a long lifetime while ensuring the conduction in a wide range between the cathode lines and the electron sources, the cathode lines are made of a material having a conductor and an insulator, and the composition of a connecting portion between the cathode line and the electron source is formed such that the conductor occupancy rate becomes equal to or more than the insulator occupancy rate.

To detect a dark current when an abnormal discharge occurs between an anode and respective electrodes, on an inner surface of a front substrate, a dark current detection electrode is formed in a state that the dark current detection electrode is positioned adjacent to the outside of a screen display region on which an anode is formed and on a plane substantially equal to a plane on which the anode is formed. Then, between an electrode terminal of the dark current detection electrode and a ground, an ammeter which detects the flow of a dark current and a DC power source having a preset voltage value which is more or less lower than a high voltage supplied to the anode are connected in series.
