| description | A liquid crystal apparatus comprises: matrix electrodes which are formed by a scanning electrode group and an information electrode group which intersect the scanning electrode group so as to face the scanning electrode group; a ferroelectric liquid crystal which is arranged between those electrode groups and is driven by an electric field applied through the electrode groups; a drive circuit having a scanning side drive circuit for sequentially generating scan selection signals to the scanning electrode group and for generating scan non-selection signals to the scanning electrodes whose scan is not selected and an information side drive circuit for generating information signals to the information electrode group synchronously with the scan selection signal in accordance with the input information; and a control circuit for controlling the drive circuit in a manner such that an interval between two scan selection signals which are continuously applied to the same scanning electrode is set to a predetermined period of time smaller than a full screen scanning period. |
