A liquid crystal device of this invention is constituted by a display cell, a compensation cell, and a pair of polarizing plates. The display cell is designed such that electrodes are respectively formed on the opposing surfaces of a pair of substrates, arranged to oppose each other through a predetermined gap, to be perpendicular to each other, alignment films are respectively formed to cover the electrodes, and a first liquid crystal material is sealed between the substrates to be twisted at a predetermined angle. The compensation cell is arranged to be stacked on the display cell. The compensation cell is designed such that a second liquid crystal material is sealed between a pair of substrates, subjected to alignment processing, to be twist-aligned in a direction opposite to the twist direction of the first liquid crystal material. The pair of polarizing plates are arranged to sandwich the display and compensation cells. A refractive index anisotropy DELTA n1 of the first liquid crystal material is 0.18 or more, and a product DELTA n1xd1 of the refractive index anisotropy DELTA n1 of a layer thickness d1 of the first liquid crystal material is 0.7 mu m or more. A product DELTA n2xd2 of a refractive index anisotropy DELTA n2 and a layer thickness d2 of the second liquid crystal material is smaller than the product DELTA n1xd1 of the first liquid crystal material.
