We have developed a 320‐dpi a‐Si:H TFT reflective stacked crossed guest‐host display, in which a thin polymer film is used to separate two orthogonally aligned nematic guest‐host liquid crystal layers, avoiding parallax and the need to drive the two layers independently. A newly designed pattern of photolithographically defined spacers that hold the thin film in a precise position and the assembly process for the stacked structure are described.
