Abstract
An OCB-mode liquid crystal device includes a plurality of pixel electrodes arranged in a matrix on one substrate of a pair of substrates, and transferring an aligned state of liquid crystal sandwiched between the pair of substrates from spray alignment in an initial state to bend alignment to perform display. During the transfer, a voltage application operation of applying an equal voltage to a plurality of pixel electrodes corresponding to an arbitrary first row, and of applying, to two pixel electrodes adjacent to both sides of one arbitrary pixel electrode among a plurality of pixel electrodes in a second row adjacent to the first row in a column direction, both voltages which are higher than or lower than an applied voltage to the one pixel electrode is performed on at least some of the plurality of pixel electrodes arrayed in a matrix. Differences between at least some of voltages applied in the voltage application operation and the voltage of an electrode formed in the other substrate of the pair of substrates are more than a threshold voltage required for the transfer to the bend alignment from the spray alignment.
