Abstract We propose a new reflective twisted nematic display mode, which is called the second minimum RTN mode. This mode has a larger dΔn value compared with the first minimum RTN mode which we proposed previously. A cell gap of 7 μm or larger can be used for this mode which makes the fabrication processing of this kind of reflective LCDs easier and more compatible with that of TN LCDs. The color dispersion in both bright and dark states of this display mode is small, and the response is reasonably fast considering the 7 μm cell gap. This display mode can be used in conjunction with TFT active matrix for high quality reflective displays for PDAs, and cell phones. It is also suitable for passive low cost applications such as watches and games.
