摘要： A projection-type display apparatus includes a light source; a color separating/synthesizing device arranged to divide light from the light source into three different color light rays; and three reflection-type display devices arranged to reflect the three different color light rays, respectively. The color separating/synthesizing device is further arranged to synthesize the three different color light rays respectively reflected by the three reflection display devices. The color separating/synthesizing device has transmittance of substantially 50% for each of a s-polarized light ray having a first wavelength and a p-polarized light ray having a second wavelength. A difference between the first wavelength of the s-polarized light ray and the second wavelength of the p-polarized light ray is equal to or less than 40 nm.

摘要： A direct-view display apparatus provides improved image quality by preventing the formation of a stripe pattern caused by parallax effects. A liquid-crystal panel for active matrix driving is disposed. A microlens array consisting of a plurality of microlenses formed in corresponding relationship to each pixel in the liquid-crystal panel is placed on a surface of a substrate of the liquid-crystal panel. A field lens and an eyepiece are disposed in this order between the microlens array and an observer. The field lens serves to converge the principal rays emerging from the microlens array in parallel with an optical axis onto the eyepiece, so that a moire pattern caused by parallax effects can be prevented from being formed and the image quality can thus be improved. Light from backlights are passed through display panels, respectively consisting of liquid-crystal cells, microlens arrays, and field lenses, and are superimposed by a crossed dichroic prism. The observer views the light superimposed by the crossed dichroic prism, i.e. a color image, through an eyepiece.

摘要： In a display device, display electrodes and insulation layers are formed on a pair of substrates with a display layer placed therebetween. In this display device, plural display picture elements are set according to the arrangement state of the display electrodes. In the display picture elements, divisions are set in the insulation layers and different dielectric constants are set for each division. Therefore, the display device has a different impedance in every division within the display picture element and the apparent threshold voltage of each division may be varied. As a result, gradations corresponding to the number of divisions within each display picture element may be displayed.

摘要： Electrochromic display device manufacture method wherein electrochromic material is deposited in a single layer on a single film of conductive material over the whole area of glass substrate and then the electrochromic material and conductive material are successively etched through a single mask which defines a display segment pattern and remains in position throughout the whole etching process, whereby etched edge portions of the different materials are in excellent alignment and there is therefore small plate area for a reverse emf cell and good display device performance is achieved. The electrochromic material may be etched by the solution employed for developing the photoresist, whereby an etching process step is eliminated.

摘要： A driving system is provided for an electrochromic display device in which the coloration state is maintained for several hours through several days of the removal of the coloration voltage as long as the electrochromic display device is held in an electrically opened state. The electrochromic display device includes a predetermined number of display segments, each of the combinations of the display segments defining a different one of the desired display patterns. The display segments placed in the coloration state are electrically connected to each other during the memory period in order to uniform the coloration degree of each of the selected display segments. In a preferred form, a detection means is provided for detecting the potential of the selected display segments, which are held in the memory coloration state. The write-in, or, coloration operation is again conducted when the potential of the selected display segments becomes higher than a preselected level.
