摘要： A liquid crystal display device includes a first twisted nematic liquid crystal cell and an optically anisotropic material sandwiched between two polarizers. A second twisted nematic liquid crystal cell or polymer film serves as the optically anisotropic material. The optically anisotropic material may be disposed on one or both sides of the first twisted nematic liquid crystal. The optically anisotropic material compensates for the elliptical polarization of the light passing through the liquid crystal cell so that the device transmits white light in the OFF state and appears black in the ON state.

摘要： A liquid crystal display device capable of displaying multiple colors in response to application of different driving voltages includes a liquid crystal cell with two polarizers and the value of the product of the optical anisotropy n of the nematic liquid crystal material and the thickness d of the liquid crystal layer is in excess of 1.1 .mu.m. A second liquid crystal cell can be included between the first cell and one of the polarizers. A driver circuit drives the liquid crystal cells by the dynamic drive method by applying a selecting voltage, a non-selecting voltage, and one or more intermediate voltages to generate the different colors.

摘要： An electro-optical device includes at least two adjacent transparent twisted nematic liquid crystal cells, each cell having a twisted nematic liquid crystal with a twist angle greater than 90.degree. between a pair of spaced apart opposed substrates with electrodes selectively disposed thereon. A linear polarizer is disposed on an exterior surface of each of the two cells. One of the two cells includes a plurality of electrodes for selectively producing a desired display. Application of a suitable voltage to the second cell compensates for changes in ambient temperature conditions or undesirable thicknesses in the liquid crystal materials of the two cells to ensure that a monochromatic display having excellent contrast is produced by the device and compensates for elliptically polarized light emitted by the first cell so that the device produces substantially linearly polarized light.
