To provide a thin liquid crystal display device featuring excellent color reproducibility. The liquid crystal display panel includes: a liquid crystal display panel outputting different colors on a per-pixel basis; and a backlight. The backlight includes: a light source; a light guide; a reflective sheet on a back side of the light guide; and a group of optical sheets including a wavelength converter and disposed between the liquid crystal display panel and the light guide. The wavelength converter has a structure where quantum dots are dispersed in a transparent medium. The wavelength converter is bonded to another optical medium by means of a diffusing adhesive. Nanoparticles for developing Rayleigh scattering are dispersed in the wavelength converter.

In an FFS liquid crystal display device, viewing angle characteristics are further improved. In an FFS liquid crystal display device, the alignment axis of a first alignment film of a first substrate and the alignment axis of a second alignment film of a second substrate are directed in the same direction. At least two of an upper polarizer, a lower polarizer, or a retardation platesatisfy conditions below. (1) The absorption axis of the upper polarizer forms an angle of one to 45 degrees inclusive with the alignment axis. (2) The absorption axis of the lower polarizer forms an angle of 91 to 135 degrees inclusive or forms an angle of 45 to 89 degrees inclusive with the alignment axis. (3) The extension axis of the retardation plateforms an angle of one to 45 degrees inclusive with the alignment axis.

An object of the present invention is to realize an image display device for color display with high luminance and high contrast. In the present invention, a unit cellis filled with electrophoresis ink including two kinds of particles different in chargeability and color being dispersed in transmissive solvent. Voltage is applied to an opposite electrode, a stacked lower electrodeand an upper electrodeand thereby electrically charged particlesand charged particlesare moved to a first openingand a second openingwhere an insulating layeris provided on the lower electrodeand the upper electrode. Thus assemblage and diffusion state of two kinds of particles are controlled. Thereby, a unit cellobtains four display colors. Since the lower electrodecan be made to be a reflecting layer covering the entire unit cell, it is possible to make the aperture ratio large and the reflection percentage large.

Electrophoresis display device

An image display apparatus configured by a display panel having an image memory element in a pixel, which achieves low power consumption. A nonvolatile image memory element, which can change the resistance value by phase change, is connected to a pixel electrodeof a liquid crystal element. The output of a thin-film transistordriven by scanning and signal electrode linesis connected to the pixel electrode. When the scanning electrode lineis selected to have a high level voltage, the thin-film transistoris turned on and a current signal flowing through the signal electrodeis sent through the image memory elementto a reference electrode line. Depending on the current value or pulse width passing through the image memory element, the resistance of the image memory elementis changed and is stored as a resistance value. A liquid crystal drive voltage to be applied to the liquid crystal elementis varied depending on the resistance of the image memory elementand an image is displayed on the liquid crystal element

Electrophoretic display and manufacturing method

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.

Projector and display system

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.

Method of reproducing three-dimensional images and three-dimensional image-reproducing device

A scintillator device and an image pickup apparatus using the scintillator, in which the scintillator for converting an input particle or electron beam image into an optical image is applied with a voltage between electrodes formed at the input plane of the electron beam and the output plane of scintillation. This voltage generates an electric field in the scintillator so that scattering of a charged particle beam in the scintillator is prevented and the resolution and S/N ratio can be improved while retaining a large amount of scintillation. Accordingly, the shift amount of low energy charged particle beams from the incident axis, which greatly influences degradation of the resolution and S/N ratio, can be suppressed.
