摘要： Signals of odd lines in progressive scanning image signals in a first frame are extracted and displayed along odd lines on a matrix-type display device such as a liquid crystal display panel. Further, signals of even lines in progressive scanning image signals in a second frame successive to the first frame are extracted and displayed along even lines on the display device. Thus, one image of a frame is displayed on the display device in two frame periods so that one of the first and second steps is performed after the other thereof is performed. Alternatively, one of the signals of odd lines are displayed along two successive odd and even lines, while one of the signals of even lines are displayed along two successive even and odd lines. The display methods can be applied to a display panel having a larger number of scanning lines than a number of signal lines. Light leakage in a liquid crystal panel including polymer dispersion liquid crystal due to lateral electric field near pixel electrodes is prevented by providing light-shielding films on the pixel electrodes. Light leakage is also prevented by providing a polarizer above one of the two sides of the panel.

摘要： A reflected light absorbing plate is divided into plural areas by light absorbing walls and is adapted to satisfy a predetermined condition among a width of one area, a thickness thereof t, and a refraction index of an absorbing plate n. The reflected light absorbing plate is applied to a display panel having a polymer dispersed liquid crystal layer as a light modulating layer via a light coupling layer. The reflected light absorbing plate and the light modulating layer are spaced by a predetermined distance taking MTF into consideration. While the light diffused at a minute area A is reflected at the interface with air, the light is absorbed by the light absorbing wall and never returns to the light modulating layer.

摘要： A liquid crystal display panel includes a counter substrate having a counter electrode and a multi-layered dielectric film both formed thereon, and an array substrate formed with pixel electrodes and thin-film transistors serving as switching elements. A layer of polymer dispersed liquid crystal material containing a UV-curable resin component and a liquid crystal component is sandwiched and sealed between the counter and array substrates. A light shielding film is formed over each thin-film transistor. The multi-layered dielectric film is a laminated structure of alternating thin-films of SiO2 and HfO2. Since the multi-layered dielectric film is of a nature capable of transmitting UV-rays of light therethrough, the UV-curable resin component positioned underneath the multi-layered dielectric film can be cured during the manufacture. Also, since the multi-layered dielectric film is of a nature capable of reflecting light of a visible region, it serves as a black matrix, reflecting the visible light modulated by the display panel. Black beads are used to keep the film thickness of the liquid crystal layer at a predetermined value. Preferably, a dielectric thin-film having a relative dielectric constant smaller than that of the liquid crystal material is formed on signal lines for transmitting signals to the thin-film transistors, to thereby accomplish an electromagnetic shield. Where color filters are to be formed on the pixel electrodes, those color filters may be formed on the signal lines to accomplish the electromagnetic shield.

摘要： In a display device, counter electrodes are formed in stripes at a position facing pixel electrodes, with a polymer dispersion liquid crystal held between the counter electrodes and pixel electrodes. When a positive-polarity signal is to be impressed to a pixel electrode, a negative-polarity voltage is fed to the counter electrode. On the other hand, when a negative-polarity signal is to be impressed to a pixel electrode, a positive-polarity voltage is added to the counter electrode. In this manner of impression voltages, a high voltage can be applied to the polymer dispersion liquid crystal layer on the pixel electrodes, so that the liquid crystal layer is turned into the transmitting state even if it is thick. Accordingly, the scattering efficiency is improved and images are displayed with high contrast as the liquid crystal layer can be made thick. If the thick transparent substrate is bonded to the counter substrate having the counter electrodes thereon, the light scattered at the liquid crystal layer is reflected by the counter substrate and returned back to the liquid crystal layer, thus eliminating the light to be scattered again.

摘要： In an optical system phase device such as .lambda./2 plate or a .lambda./4 plate is used to convert S polarization to P polarization and vice versa. In the projection display, a white light emitted from a light source is separated by a color separation optical system, including dichroic mirrors or a dichroic prism, into three primary colors which are modulated by optical modulation elements. Then, the modulated lights are synthesized by a color synthesis optical system and projected by a projection element onto a screen. When appropriate plates are inserted appropriately in the optical system of the projection display, the conversion between S and P polarization occurs and an optical bandwidth becomes narrow, and color purity can be improved. A thick transparent plate is preferably adhered to the optical modulation element. A light absorption film is applied to an ineffective plane of the transparent plate. The phase device is preferably inserted between an optical modulation element and a transparent plate or the like to improve contrast. The invention can be applied to liquid crystal panels such as liquid crystal/resin display panels, light beam writing type display panel or micro mirror display panel. Preferably, the phase device is set to be rotatable so as to adjust contrast appropriately.
