A liquid crystal device has inorganic alignment layers ( 36, 42 ) disposed on a surface of a liquid crystal layer side of a pair of the substrates, when the range of the average pre-tilt angle theta of liquid crystal molecules 50 a of the liquid crystal layer is 5 degrees <=theta<=20 degrees, twist angle phi of the liquid crystal molecules ( 50 a) of the liquid crystal layer, cell gap d, and helical pitch P of the liquid crystal molecules of the liquid crystal layer satisfy the relationship of (0.6/360)phi<d/P<(1.4/360)phi, and when the range of the average pre-tilt angle theta of liquid crystal molecules 50 a of the liquid crystal layer is theta>20 degrees, twist angle phi of the liquid crystal molecules ( 50 a) of the liquid crystal layer, cell gap d, and helical pitch P of the liquid crystal molecules of the liquid crystal layer satisfy the relationship of (0.8/360)phi<d/P<(1.6/360)phi.
