Abstract:
1. A method for driving a liquid crystal device having an optically compensated bend mode and including an image display area including a plurality of pixel electrodes two-dimensionally arranged (1) in a row direction in which a plurality of scanning lines extend and (2) in a column direction in which a plurality of data lines extend and including a counter electrode opposed to the plurality of pixel electrodes with a liquid crystal being disposed between the plurality of pixel electrodes and the counter electrode, the method comprising: performing an initial transition of an alignment of the liquid crystal from a splay alignment to a bend alignment, the initial transition including a first inversion driving mode for inverting polarities of voltages applied to the plurality of pixel electrodes relative to a voltage level of the counter electrode, and a second inversion driving mode for switching the first inversion driving mode, the period of the first inversion drive mode being less than or equal to 30 frames, and the period of the first inversion drive mode being 12 or 24 frames, wherein an arrangement of a set of pixel electrodes of the plurality of pixel electrodes in which the polarities of voltages applied to the set of pixel electrodes of the plurality of pixel electrodes relative to the voltage level of the counter electrode are the same for each pixel electrode of the set of pixel electrodes of the plurality of pixel electrodes in the second inversion driving mode is different from an arrangement in the first inversion driving mode, the first inversion driving mode and the second inversion driving mode are executed sequentially during the initial transition, one of the first and second inversion driving modes is a frame inversion-driving mode for applying voltages having relatively identical polarities to all the plurality of pixel electrodes, and the other of the first and second inversion driving modes is a different inversion driving mode.
