We propose novel optical configurations of liquid crystal cells in double cell gap structure for transflective displays. The transmissive part as well as the reflective part is designed in the wide-band quarter-wave structure to achieve the good dark state. We found that in-plane switching of the proposed structure can provide a perfect bright state, although not only in-plane switching but also vertical switching can be used to achieve the bright state. It is also expected that wide viewing angle can be achieved at the same time by employing the in-plane switching mode.
