摘要： In a color liquid crystal display device, the shape of a color filter cannot be seen and coloring of areas other than a display area due to leaking light is prevented. By making a first and second segment electrodes in a two layer construction, it becomes possible to display two different display image planes in different colors with only the single layer type color liquid crystal display device. Further, sufficient contrast can be obtained by using a liquid crystal element for compensation. It is also possible to display two kinds of display image planes, namely a color display image plane and a black and white display image plane. Two kinds of color display image planes can be displayed because the color liquid crystal display device is made in a two layered construction. A so-called normally black display and normally white display can be switched. Further, when the display state is switched between normally black display and normally white display, the background color changes and it is possible to maintain the same display color. Further display colors can be doubled as compared to the example of the prior art.

摘要： A color liquid crystal display device in which a color filter is provided over the entire surface of the glass substrate. In a first embodiment, display electrodes extend over a plurality of color filter sectors to form segment electrodes. In a second embodiment, the transmissivity of light passing through the liquid crystal layer can be varied in levels by making the display electrodes in two-layer, operating voltage on each of the electrodes independently, and varying in levels the amplitude of voltage applied on the liquid crystal layer by the display electrodes. In a third embodiment, the amount of light transmitted in the display area of a color filter sector is controlled by two or more display electrodes which divide up the display area.

摘要： In a liquid-crystal color display having a pair of light-transmitting substrates disposed opposite each other sandwiching a liquid crystal layer between them and color selecting members and a light blocking member provided on one of the pair of light-transmitting substrates, light-transmitting pixel electrodes are disposed on the liquid crystal layer side of one of the light-transmitting substrates. The pixel electrodes disposed adjacent to each other correspond to different color selecting members and are formed extending into each other's display area in alternating fashion. Accordingly, display patterns formed by adjacent pixel electrodes are allowed to overlap each other, thus making it possible to increase the number of display patterns per unit display area.

摘要： For recording an image on a photosensitive material with the employment of a liquid crystal device, the device used therein is conventionally constructed so as to modulate an amount of light rays transmitted therethrough or reflected thereby commonly by the control of an amount of electric voltage impressed to the liquid crystal device and/or impression timing or frequencies thereof. In this instance, although the light rays irradiated are considered normally as parallel, they are not intact strictly parallel light rays, and consequently unless the light rays transmitted from the device are converged by Selfoc lens arrays and the like, sufficient resolution can hardly be obtained on the photosensitive material on account of the light rays still having comparatively large diffusion coefficients. Since the liquid crystal device made in accordance with this invention is provided with its own image formation abilities, contact exposure with the photosensitive material is possible, and image formation optical systems which have been used in conjunction with the device is safely and advantageously eliminated, whereby parallelism limitations imposed on the irradiated rays can be reduced, and optical mechanisms therefor could be compact and have remarkably improved efficiencies.

摘要： A method for driving a twisted nematic type liquid crystal shutter, the liquid crystal shutter having a pair of transparent substrates held opposite to each other; a pair of patterned transparent electrodes each formed on the planes of the transparent substrates and arranged opposite to each other so that the overlapping parts of the patterns form display pixels; a pair of aligning film each formed on the pattern of the transparent electrode and on the plane; a liquid crystal material contained in a space between the transparent substrates; and a pair of transmission type polarizers each arranged on the outside plane of the transparent substrate which is counter to the plane on which the patterned transparent electrode is formed, comprising the steps of: applying an electric voltage to establish static or multiplex driving to the transparent electrodes so as to prevent the transmission of incident light when no image signal is received from an external apparatus; and preventing the application of the electric voltage to transparent electrodes which relate to the pixels selected by the image signal so as to permit the transmission incident light when the image signal is received from the external apparatus.

摘要： A liquid crystal display device in which a display area, a connecting area and a remaining area are set separately in ON (display) and OFF (non-display) states. Accordingly, even in the liquid crystal display device wherein a positive display (normally white display) is made, a negative display (normally black display) can be effected by switching the ON and OFF states. Similarly, in the liquid crystal display device wherein the negative display is made, it can be switched to the positive display. Since the ON and OFF states of a liquid crystal layer corresponding to each of the three color filters of red, green and blue can be set optionally, eight color displays are possible by combination of the three colors. The segment side and common side transparent electrodes are formed respectively in two divisions, so that the transparent electrode can be formed by a conventional patterning technique without using the precise patterning technique.
