Abstract:
An object of the present invention is to provide a liquid crystal device which can suppress cross-talk and can maintain uniformity of the display quality within the screen, and for which problems such as insufficient writing do not occur. In a liquid crystal light valve of the invention, an image signal for which the polarity is inverted for each one horizontal period, is supplied to each data line, and for each horizontal period plural pulse signals which each rise at a different timing, are supplied to each of plural scanning lines while skipping one part of the scanning lines. Moreover driving is such that in any one horizontal period, plural scanning lines, to which is supplied a pulse signal rising at a timing corresponding to an application period of a positive polarity potential, are adjacent to each other, and plural scanning lines, to which is supplied a pulse signal rising at a timing corresponding to an application period of a negative polarity potential, are adjacent to each other.
