In this paper, a new design of single cell gap transflective liquid crystal display (LCD) using twist nematic (TN) and low twist nematic (LTN) modes has been proposed, which has a simple configuration and only the bottom alignment layer need to be patterned by photoalignment technology to produce domains. This configuration shows high contrast, wide viewing angle, fast response and high transmittance / reflectance. The Transmittance versus Voltage Curve (TVC) and Reflectance versus Voltage Curves (RVC) are perfectly matched. Also the fabrication process is easy.
