PROBLEM TO BE SOLVED: To provide a liquid crystal device advantageous to reduce costs by simplifying a driving method and device therefor when adjusting a refractive index of the liquid crystal device, and to provide the driving method and device therefor. SOLUTION: The liquid crystal device 10 is comprised of a 1st transparent substrate 1002 and a 2nd transparent substrate 1004 faced to each other, a liquid crystal 1014 filled between the 1st and 2nd substrates 1002, 1004, a 1st transparent electrode 1006 formed on the surface of the 1st transparent substrate 1002 facing the 2nd transparent substrate 1004, and a 2nd transparent electrode 1008 formed on the surface of the 2nd substrate facing the 1st transparent substrate 1002. The potential difference between the 1st and 2nd driving signals S1, S2 is applied to the liquid crystal 1014 by making a time difference between the driving signals S1, S2 consisting of the rectangular waves to be applied to the 1st and 2nd transparent electrodes 1002, 1004.
