摘要： A driving method is described for a liquid crystal display device of the active matrix type which includes a pair of substrates and a liquid crystal disposed between the substrates so as to form a matrix of pixels provided with a plurality of pixel electrodes arranged in rows and columns, a plurality of row electrodes and a plurality of column electrodes, respectively, for applying a voltage to the pixels via the pixel electrodes, and a plurality of active elements each provided to a pixel and connected to a pixel electrode, a row electrode and a column electrode, respectively. The driving method includes a field-inversion drive scheme wherein the liquid crystal display device is driven while inverting a polarity of voltage applied to each pixel every picture scanning field. The voltage applied to each pixel is corrected based on a voltage to be applied to a column electrode connected to the pixel for a period from a time of selecting an active element at the pixel in a field period to a time of selecting the active element in a subsequent field period.

摘要： There is a demand for preventing display quality of a display apparatus from deteriorating. When charged particles (9) are attracted to a first electrode (3), the distribution density may not become uniform over the entire area A1 and only the distribution density in the periphery of the first electrode (3) (see reference numeral A3) may be locally reduced. The present invention places a colored layer (5) having the same color as the color of charged particles in this area A3. Therefore, even if the distribution density is low, the low density is hardly visually recognized, making it possible to prevent the display quality from deteriorating.
摘要翻译：需要防止显示装置的显示质量恶化。当带电粒子（9）被吸引到第一电极（3）时，分布密度在整个区域A 1上可能不均匀，并且仅在第一电极（3）周围的分布密度（参见附图标记A3 ）可能会局部减少。本发明在该区域A 3中设置与带电粒子的颜色相同颜色的着色层（5）。因此，即使分布密度低，几乎不可视地识别低密度，从而可以防止显示质量恶化。

摘要： A layer of discotic liquid crystal having a molecular structure including a disk-shaped core and plural side chains connected to the core is disposed in contact with a substrate boundary provided with a homeotropic alignment power for aligning the side chains of the discotic liquid crystal molecules vertically to the boundary, whereby a uniform columnar structure vertical to the substrate of the discotic liquid crystal is formed. As a result, a discotic liquid crystal device having a stable homeotropic monodomain alignment can be formed from a wide scope of discotic liquid crystal materials.

摘要： A liquid crystal device suitable for analog gradational display according to active matrix drive is formed using a chiral smectic liquid crystal. The voltage-transmittance (V-T) characteristic change accompanying a cell thickness change can be minimized to allow the production of such a liquid crystal device at a higher yield. In the liquid crystal device, the liquid crystal is placed in such an alignment state that the liquid crystal is monostabilized under no voltage application and is tilted in response to the application of voltages of opposing polarities so that the saturation voltage becomes larger at small cell thickness (liquid crystal layer thickness).
