A liquid crystal device, and a method and an apparatus for driving the same in which the refractive index of the liquid crystal device is adjusted using a simple driving method and apparatus, which is advantageous in that the cost is reduced, are provided. A liquid crystal device ( 10 ) includes a first transparent substrate ( 1002 ) and a second transparent substrate ( 1004 ) that face each other, a liquid crystal ( 1014 ) filled between the first and second transparent substrates ( 1002, 1004 ), a first transparent electrode ( 1006 ) formed on a surface of the first transparent substrate ( 1002 ) that faces the second transparent substrate ( 1004 ), and a second transparent electrode ( 1008 ) formed on a surface of the second transparent substrate ( 1004 ) that faces the first transparent substrate ( 1002 ). First and second driving signals (S 1 , S 2 ) of square waves are applied to the first and second transparent electrodes ( 1002, 1004 ) with a time interval t (sec) therebetween. Thus, the potential difference between the first and second driving signals (S 1 , S 2 ) is applied to the liquid crystal ( 1014 ).
