We have developed a transflective liquid crystal display (LCD) having a single cell gap and a single LC mode by adopting a patterned retardation layer. In our transflective configuration, a single LC mode of the 60° twisted nematic LC was used for both transmissive and reflective applications. The patterned retardation layer was fabricated using a reactive mesogen by photo‐patterning. The measured electro‐optic characteristics of our transflective LC cell agree well with numerical simulations. Particularly, the transmittance was found to show similar behavior to the reflectance.
