摘要： A liquid crystal display device includes a liquid crystal cell including a liquid crystal layer twist-aligned at 90° sandwiched between a pair of substrates, first and second polarizing layers arranged to sandwich the liquid crystal cell therebetween so that their absorption axes set to parallel with directions crossing aligning treatment directions of the substrates at 45°, and viewing angle compensating plates respectively arranged between the polarizing layers and the liquid crystal cell. A total value of retardations in a thickness direction, defined as a value of a product of a phase difference within a plane perpendicular to substrate surfaces of the liquid crystal cell and a layer thickness, of optical layers present between the polarizing layers is set to a value that substantially cancels out a retardation in a liquid crystal layer thickness direction when a saturation voltage is applied to the liquid crystal layer.

摘要： A liquid crystal layer is sealed between a pair of substrates on which opposite electrodes are formed. The liquid crystal layer is formed of a liquid crystal which exhibits an antiferroelectric phase while the liquid crystal is in a bulk state. When the liquid crystal is sealed between the substrates as the liquid crystal layer, the liquid crystal exhibits a ferrielectric phase wherein liquid crystal molecules aligned in a first state of being aligned in a first direction and liquid crystal molecules aligned in a second state of being aligned in a second direction are present in predetermined order. In accordance with the polarity and magnitude of a voltage applied between the opposite electrodes, the ratio of the number of liquid crystal molecules aligned in the first state to the number of liquid crystal molecules aligned in the second state varies such that the direction of the director of the liquid crystal layer varies continuously. Gradation display can be achieved by detecting a variation in the director through the use of a pair of polarization plates arranged in a crossed Nicols fashion.

摘要： A color liquid crystal display device includes a front substrate having a surface on which a plurality of pixel electrodes are arranged in the form of a matrix, and two-terminal nonlinear resistor elements are arranged to correspond to the pixel electrodes. An aligning film covers the pixel electrodes and the nonlinear resistor elements. A rear substrate opposes the front substrate and has an inner surface on which counter electrodes are arranged to oppose the pixel electrodes, for forming a plurality of pixels. An aligning film covers the pixel and counter electrodes. A liquid crystal layer is sandwiched between the front and rear substrates and has an initial aligned state in which liquid crystal molecules are aligned in a predetermined direction by the aligning films. A polarizing member is arranged on an outer side of the front substrate such that a polarization axis of the polarizing member crosses an aligning direction of liquid crystal molecules adjacent to the aligning film on the front substrate side at an angle other than a right angle. A reflecting member is arranged on the rear substrate side. The two-terminal nonlinear resistor elements have one terminal connected to the pixel electrode, and another terminal receiving a signal voltage.
