Liquid crystal apparatus

A liquid crystal apparatus, comprising:

• a) a liquid crystal device comprising a group of first electrodes, a group of second electrodes intersecting the first electrodes, and a ferroelectric liquid crystal disposed between the group of first electrodes and the group of second electrodes so as to form a pixel at each intersection of the first and second electrodes;
• b) first means for sequentially applying a scanning selection signal to the first electrodes;
• c) second means for simultaneously applying data signals to the second electrodes in synchronism with the scanning selection signal;
• and
• d) third means for controlling the data signals so that a prescribed number of rightmost or leftmost second electrodes is designated among the group of second electrodes to form a marginal region, and other second electrodes among the group of second electrodes are designated to form a display region which forms pixels in a bright state or dark state when supplied with data signals, and said electrodes in the marginal region are supplied with data signals so as to first form a dark state and then form a bright state at the pixels on a particular first electrode under application of the scanning selection signal, thereby (i) forming a bright state in the marginal region including all the pixels formed at the intersections of the first electrodes and the designated prescribed number of second electrodes and (ii) forming a desired display state in the display region including pixels in the bright or dark state depending on given display data signals after the completion of one cycle of scanning of the first electrodes, wherein the bright state at a pixel in the marginal region is identical to the bright state at a pixel in the display region and wherein said data signals applied to the second electrodes in the marginal region include a pulse for forming said bright state in said marginal region, wherein said pulse has a pulse width which is larger than a maximum pulse width of the data signals applied to the second electrodes in the display region.
