Abstract
A liquid-crystal display device is reported combining a polarizer, a deformation of aligned phases (DAP) cell, a twisted nematic (TN) cell, and an analyzer in series arrangement. The color of the transmitted light can be modulated by the application of voltage to the DAP cell. The transmission properties of the device can be switched from the DAP mode for crossed polarizers to that for parallel polarizers by the application of voltage to the TN cell. This improves control of the transmitted color.
