摘要： PURPOSE:To drive ferroelectric liquid crystal in scatter mode on time-division basis by using a DC nonselection voltage for the voltage waveform of a scanning electrode when the scanning electrode is not selected or an AC selection voltage which has an amplitude center at the nonselection voltage when the scanning electrode is selected, and using an AC voltage which is in phase or out of phase with the selection voltage for the voltage waveform of a signal electrode. CONSTITUTION:A figure A4 shows a voltage waveform impressed to the signal electrode 4 when a display is made so that the intensity of scattered light decreases in the order of intersections B1, B2, and B3 of the signal electrode 4 and scanning electrodes 1, 2, and 3. The waveform is out of phase with the AC waveform of the selection voltage in a period 6-1 (7-1), out of phase in the front half of a period 6-1 (7-2) and in phase in the latter half, and in phase in a period 6-3 (7-3). Waveforms impressed to picture elements B1, B2, and B3 are shown by A1-A4, A2-A4, and A3-A4. The intensity values of scattering at the respective points are shown by C1, C2, and C3. The selection voltage 11 and nonselection voltage 13 are switched by a switch 12. The waveform of the selection voltage or the waveform obtained by inverting the selection voltage by an inverter 15 is switched in synchronism with the selection position of the scanning electrodes according to display contents.

摘要： PURPOSE:To increase the service life of a liquid crystal by disposing the third metal film having a finite light transmission factor which is not zero with plane shape substantially equal to the second conductor film in contact with the second film under the second film, thereby obtaining AC property of a voltage applied to the liquid crystal to be applied with a voltage. CONSTITUTION:A Ta film is formed in a thickness of approx. 50nm on a substrate 1, and thermally oxidized as a protective film 2 of Ta2O5. The Ta film of the first metal film is formed at approx. 240nm thick on the protective film, and etched to form the first pattern 3. The surface of the film 3 of the first metal film is subjected to an anodic oxidation (by applying 30V for 5min in 0.1% citric acid solution) to form a Ta2O5 film 4 for a diode of approx. 50nm thick. Then, a metal film 6 of Cr, Mo, Ta is formed in sufficient thickness to establish a work function (approx. 5nm), and a transparent conductive film 5 of In2O3 is laminated at approx. 100nm. The film 5 and a metal film 6 are etched with a resist film patterned in the shape of the second pattern 7 to obtain the second pattern 7 in which the layer 6 and 5 are laminated.

摘要： PURPOSE: To perform projection in a light room by arranging polarizing plates in front of a screen and noise light so that the transmission axes of the polarizing plates cross each other nearly at right angles and the polarization direction of projection light is nearly parallel to the transmission axis of the polarizing plate in front of the screen.
CONSTITUTION: Light projected from in front of the screen 1 is transmitted through the before-screen polarizing plate 2 which has the transmission axis nearly in parallel to the polarization direction of projection light without large attenuation to form an image on the screen surface, and the light is reflected to reach an observer 7. On the other hand, the noise light emitted by the noise light generator 4 consisting of a noise light generation source 5 such as a window and the before-noise-light polarizing plate 6 which transmits only polarized light crossing the transmission axis of the polarizing plate 2 nearly at right angles is attenuated greatly by the polarizing plate 2, so the quantity of light reaching the screen surface is reduced greatly. Consequently, the brightness of a display image on the surface of the screen 1 becomes larger than that of the noise light, so projection in a light room becomes possible.

摘要： PURPOSE:To improve the quality of a color liq. crystal display panel displaying natural color or limited color by changing the thickness of the liq. crystal layer correspondingly to color filters so that the thickness of parts of the layer corresponding to color filters selecting a longer wavelength is made relatively large. CONSTITUTION:A liq. crystal layer 11 is held between substrates 41, 42 having electrodes 43, 47 and orienting layers 44, 46, respectively. At this time, color filters 45 corresponding to the three primary colors R, G, B are formed on the substrate 41, and the thickness of the substrate 42 is changed by etching so as to change the thickness dR, dG, dB of the liq. crystal layer 11. The most suitable conditions include dR:dG:dB=lambdaR:lambdaG:lambdaB. The ratio among the thicknesses of the liq. crystal layer is made equal to the ratio among the selected wavelengths of three colors.

摘要： PURPOSE:To eliminate an additional memory and also to obtain a liquid crystal display device with high reliability by setting a liquid crystal impressed voltage at a time other than a display expansion period in the vicinity to zero. CONSTITUTION:In order to expand periods between the 120-th and the 239-th of a video signal by utilizing a display expanding function, a scanning electrode 6-1 is brought into the selecting state as shown in (6-1)' for 1H of the period 120 by a control section 12 at first and other scanning electrodes 6-2-6-120 are brought into the non-selection state. A signal electrode selection signal or a signal electrode non-selection signal is impressed in response to the content of the video signal to signal electrodes 7-1-7-M. A voltage applied to the scanning electrodes 6-1-6-120 and the signal electrodes 7-1-7-M is made respectively equal so as to zero nearly the liquid crystal voltage at a period other than periods 120-239. Since the voltage impressed to the liquid crystal is nearly zero at a time other than the expanded period, crosstalk is not increased and the contrast corresponding to 120 divisions is attained.

摘要： PURPOSE: To reduce the number of elements of a driving circuit by using at least ≥one analog line memory and plural analog pulse width converters.
CONSTITUTION: An R(G, B) chrominance signal formed at a synchronous separation/color separation circuit 1 is not digitized and transmitted to an analog line memory 22-R(G, B) while keeping analog quantity. The analog line memory R-22 stores the R(G, B) chrominance signal for one line's share in analog quantity and transmits the analog value to analog latches 21-1-R(G, B)∼21-n-R(G, B) in parallel during the blanking period of a horizontal scanning line, for example, in synchronizing with a signal of a control circuit 23. An analog switch keeps said data during the horizontal scanning period and outputs the data to analog pulse width converters 20-1-R(G, B)∼20-n-R(G, B). The analog pulse width converter 20-1-R compares the analog data held as above with a compared analog data changing with time, modulates the pulse width of the output pulse in response to the two values and controls an effective voltage impressed to a column electrode.
