摘要

A liquid crystal device includes, peripheral electrodes including three electrodes for ion trapping, and a transistor coupled to each of the three electrodes. A common signal (COM signal) that varies between a first potential and a second potential in a first period is applied to a counter electrode. A driving signal that varies between a third potential and a fourth potential is input to the transistor. The driving signal is coupled to or uncoupled from the peripheral electrodes by the transistor in a unit of a duration equal to or less than ? of the first period. AC signals varying between a positive-polarity potential and a negative-polarity potential, with a potential of the common signal being a reference, in a second period longer than the first period, are applied to the three electrodes of the peripheral electrodes, in a state where phases of the AC signals are shifted mutually.

說明書

In the Example 2, the driving signal S1 of which potential varies between ?5 V and +5 V is applied to the first electrode 121, taking a potential of the COM signal to which the common inversion driving is reflected as the reference. Thus, from the time t0 to the time t1, the COM signal is at the first potential (5V) and the potential of the driving signal S1 is ?5 V, and hence, the potential of the first electrode 121 relative to the COM potential is 0 V as illustrated in FIG. 9. From the time t1 to the time t7, the COM signal varies between the second potential (0 V) and the first potential (5 V) in unit of one vertical duration. On the other hand, the potential of the driving signal S1 is +5 V and stays constant, and hence, the potential of the first electrode 121 varies between +5 V and +10 V in unit of one vertical duration. From the time t7 to the time t13, the COM signal varies between the second potential (0 V) and the first potential (5 V) in unit of one vertical duration. On the other hand, the potential of the driving signal S1 is ?5 V and stays constant, and hence, the potential of the first electrode 121 varies between ?5 V and 0 V in unit of one vertical duration of the COM signal. From the time t13 to the time t14, the COM signal is at the second potential (0 V) and the potential of the driving signal S1 is +5 V, and hence, the potential of the first electrode 121 relative to the COM potential is +5 V. In other words, the AC signal applied to the first electrode 121 according to Example 2 is an AC signal of which potential varies, taking a potential of the COM signal as a reference, between 10 V at the maximum on the positive polarity side and ?5 V at the maximum on the negative polarity side in unit of one vertical duration of the COM signal.
