摘要： A liquid crystal element improved to reduce hysteresis and after-image by relaxing electronic polarization at an interface between liquid crystal and an orientation film, and hence to enhance an image quality and realize smooth display of a dynamic image irrespective of a material of liquid crystal. The liquid crystal element includes a plurality of base bodies each having a liquid crystal orientation film, the base bodies being opposed to each other on the orientation film side with a specific gap put therebetween; and liquid crystal disposed in the gap; wherein each of the orientation films has a property capable of relaxing polarization at an interface with the liquid crystal. The liquid crystal orientation film may be composed of an orientation film having low polarization such as a SiOx oblique vapor-deposition film or may be composed of a stacked film in which a thin film having low polarization and capable of relaxing polarization at an interface with the liquid crystal or an organic complex having an electric conductivity of 1.2×10−8 S/cm or more is stacked on an orientation film.

摘要： A driving method for a liquid crystal device includes the steps of providing a first substrate with a unidirectionally aligned data electrode group and a second substrate with a select-electrode group aligned perpendicularly to the data electrode; applying a select pulse to the select electrodes; and providing a pause corresponding to at least one line before a data-pulse sequence is applied to the data-electrode group. The select pulse can be synchronized with the data-pulse sequence by shifting them a half line relative to each other so that the select pulse and the data pulse have opposite polarity in relation to each other. Alternatively, the select pulse is applied while the data pulse sequence is applied to the data electrode group. In the latter case, the time and/or voltage is determined so as to offset the effects of the reversed electric field generated during switching of the liquid crystal.
摘要翻译：液晶装置的驱动方法包括以下步骤：提供具有单向排列数据电极组的第一衬底和具有与数据电极垂直排列的选择电极组的第二衬底; 对选择电极施加选择脉冲; 并且在将数据脉冲序列应用于数据电极组之前提供对应于至少一行的暂停。选择脉冲可以与数据脉冲序列同步，通过将它们相对于彼此移动一半，使得选择脉冲和数据脉冲相对于彼此具有相反的极性。或者，当将数据脉冲序列施加到数据电极组时施加选择脉冲。在后一种情况下，确定时间和/或电压以抵消在液晶切换期间产生的反向电场的影响。
