摘要： In order to charge and discharge parasitic capacitance of a source signal line sufficiently and program a predetermined current value into a pixel transistor, it is necessary to output a relatively large current from the source driver circuit. However, if such a large current is passed through the source signal line, the value of this current is programmed into the pixel, causing a larger than desired current to flow through an EL element. For example, if a 10 times larger current is used for programming, a 10 times larger current flows through the EL element, and thus the EL element illuminates 10 times more brightly. To obtain predetermined emission brightness, the time during which the current flows through the EL element can be reduced to 1/10 of one frame (1 F). This way, the parasitic capacitance of the source signal line can be charged and discharged sufficiently and the predetermined emission brightness can be obtained.

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.
