Title:
LIQUID CRYSTAL DEVICE, DRIVE METHOD THEREFOR, AND PROJECTION TYPE DISPLAY APPARATUS
Document Type and Number:
Japanese Patent JP2004177930
Kind Code:
A
Abstract:

To provide a liquid crystal device which suppresses cross-talk, maintains uniformity of the display quality within the screen, and prevents problems such as insufficient writing.

In a liquid crystal light valve of the invention, an image signal whose polarity is inverted for each one horizontal period is supplied to each data line and, for each horizontal period, a plurality of pulse signals each of which rises at a different timing are supplied to each scanning line while skipping one part of the plurality of the scanning lines. Driving is carried out in such a manner that, during any one horizontal period, a plurality of scanning lines, to which a pulse signal rising at a timing corresponding to an application period of a positive polarity potential is supplied, are adjacent to each other, and a plurality of scanning lines, to which a pulse signal rising at a timing corresponding to an application period of a negative polarity potential is supplied, are adjacent to each other.
