| http://www.w3.org/ns/prov#value | - The alternating-current signal VLCON, as shown in FIG. 13, is a signal inverting at a predetermined time interval with reference to the counter electrode potential VCOM as a reference, and is an alternating-current voltage capable of turning on the LC section 24A. Meanwhile, the direct-current signal VLCOFF is a direct-current voltage capable of turning off the LC section 24A. These alternating-cu
