Abstract: 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 cell 111 is filled with electrophoresis ink including two kinds of particles different in chargeability and color being dispersed in transmissive solvent 107. Voltage is applied to an opposite electrode 103, a stacked lower electrode 104 and an upper electrode 105 and thereby electrically charged particles 108a and charged particles 108b are moved to a first opening 106a and a second opening 106b where an insulating layer 110 is provided on the lower electrode 104 and the upper electrode 105. Thus assemblage and diffusion state of two kinds of particles are controlled. Thereby, a unit cell 111 obtains four display colors. Since the lower electrode 104 can 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.

Abstract: 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 1, which can change the resistance value by phase change, is connected to a pixel electrode 25 of a liquid crystal element 5. The output of a thin-film transistor 17 driven by scanning and signal electrode lines 7, 9 is connected to the pixel electrode 25. When the scanning electrode line 7 is selected to have a high level voltage, the thin-film transistor 17 is turned on and a current signal flowing through the signal electrode 9 is sent through the image memory element 1 to a reference electrode line 15. Depending on the current value or pulse width passing through the image memory element 1, the resistance of the image memory element 1 is changed and is stored as a resistance value.

Abstract: In a portable information processing apparatus, frames 5 and 6 on which display devices are mounted are pivotally supported in a coupling portion 3 constituted by a hinge mechanism in an openable/closable manner, while the display devices have main displays 1 and 2, which perform printing with high-resolution quality. While the coupling portion 3 is set to a fulcrum, the main displays 1 and 2 are brought into such a two-page spreading condition for the use, and are overlapped with each other, and are folded into two displays for closure, so that the portable information processing apparatus can be carried. Since a rotation portion 4 is rotated, an image which is displayed on the main displays 1 and 2 can be changed. Both a power switch 7 and a function switch 8, which are necessary switches and the like, are mounted on an edge portion of the frame 6.

Abstract: 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.
