摘要： PROBLEM TO BE SOLVED: To provide an active matrix liquid crystal display device permitting to display a high quality moving picture and permitting also low power consumption. SOLUTION: In the active matrix liquid crystal display device, one frame period is divided into plural sub-frame periods, and the pixels of all the lines to be scanned during the sub-frame periods are selected in a batch, and in synchronization with this batch selection, an erase signal for uniformalizing the pixel potentials is written in the pixels selected in a batch. Moreover, since the device has a function of correcting and converting the original picture signal levels in the direction in which a level difference from the erase signal level increases, and writes this converted signal in each pixel as a picture signal, the response speed of the liquid crystal is accelerated, and the luminance of the liquid crystal panel is improved. Further, since the erase signal is written in a batch in the pixels of all the lines to be scanned during the sub-frame periods, the device can be made to operate at a driving frequency equivalent to conventional one.

摘要： PURPOSE: To obtain a wide visual angle by adding an optically active compd. which gives a helical structure to the orientation of liquid crystal molecules of a liquid crystal having negative dielectric anisotropy, forming a liquid crystal layer and orienting the liquid crystal molecules perpendicular to the plane of an orienting film. CONSTITUTION: Orienting films 23, 27 are formed by applying org. silane compd. films on transparent electrodes 22, 26 formed on glass substrates 21, 25, respectively. These substrates are disposed with the orienting films 23, 27 facing each other to form a space, and a liquid crystal layer 32 is held in this space to constitute a liquid crystal cell 34. This liquid crystal layer is prepared by adding an optically active compd. which gives a helical structure to the orientation of liquid crystal molecules, for example, by adding cholesterisnonate by 2%, to a liquid crystal material having negative dielectric anisotropy. Further, polarizing plates 28, 29 with the polarization directions perpendicular to each other are disposed on the both sides of the liquid crystal cell 34 to obtain a liquid crystal element 35. The liquid crystal molecules in the liquid crystal layer 32 are oriented perpendicular to the film plane of the orienting films 23, 27. Thereby, when enough voltage is applied, the liquid crystal molecules are released from the control of the orienting films so that the orienting axes of liquid crystal molecules are randomly distributed in the plane parallel to the substrate plane.

摘要： PURPOSE:To obtain good characteristics with small hysteresis and high contrast by forming a composite film comprising a polymer matrix and a liquid crystal which is carried on fine particles with an anisotropic shape and dispersed and held in the polymer matrix. CONSTITUTION:The liquid crystal dispersed in the polymer matrix is carried on fine particles having an anisotropic shape (such as nonspherical shape) and is formed into liquid crystal drops according to the shape of fine particles. Namely, when the polymer matrix precursor is polymerized to cause the phase separation between the liquid crystal and the polymer matrix, the liquid crystal grows with the fine particles as nuclei. Therefore, the shape of liquid crystal drops necessary to obtain the optimum electro-optical characteristics is controlled by changing the shape and kinds of fine particles. When the fine particles are in an anisotropic shape, the liquid crystal molecules are easily oriented in a specified longitudinal direction and the liquid crystal drops are easily made to have an anisotropic shape. Thereby, the optimum electro-optical characteristics with high contrast and small hysteresis are obtd.

摘要： PURPOSE:To prevent the liquid crystal at a light-unirradiated part from being inverted at the time of optical writing and to perform the optical writing with high definition by providing a no-voltage impression time halfway in optical scanning. CONSTITUTION:A light source combined with a two-dimensional scanner is used, and the period wherein a voltage impressed to an electrode or liquid crystal layer at least once, preferably, as many times vertical scanning lines is hold at zero is provided in a write period 2 so as to suppress the inversion of the liquid crystal layer at the light unirradiated part which causes a problem when the optical write time 2 is long. In this no-voltage period 3, the DC voltage impressed continuously to the liquid crystal layer at the light-unirradiated part in the write period 2 is interrupted and accumulated charges are all removed to inhibit the orientation of the liquid crystal layer from varying while external energy applied to the part does not exceed the product CPA of electric field intensity and voltage impression time as a critical value, thereby obtaining extremely high effect to the high-definition optical recording.
