Specifically, the first predeterminated voltage is more than the second predeterminated voltage.And the second default driving voltage can be no-voltage,
Can be Relative Zero voltage, the 3rd default driving voltage is identical with the second default driving voltage.Apply the first default driving voltage
Driving electrodes 140 and the face electrode or strip electrode in second electrode structure between voltage difference driving liquid crystal layer 13 in it is corresponding
Liquid crystal molecule deflect to form light shielding part, and because the 3rd default driving voltage is identical with the second default driving voltage, application the
Voltage is not present between face electrode or strip electrode in the driving electrodes 140 and second electrode structure of two default driving voltages
Difference, corresponding liquid crystal molecule deflection in liquid crystal layer 13 can not be driven, forms transmittance section.It is, of course, understood that this practicality is new
The 3rd default driving voltage in type embodiment can also differ with the second default driving voltage, but close, both voltage differences
It is sufficiently small, to be not enough to drive liquid crystal molecule to deflect and be defined, so positioned at the driving electricity for applying the second default driving voltage
The liquid crystal molecule between face electrode or strip electrode in pole and second electrode structure will not deflect, and form transmittance section.
In the utility model embodiment, as shown in Fig. 2 the width of driving electrodes is d1, two adjacent driving electrodes
