We developed a wide‐viewing twisted‐nematic (TN) liquid crystal display (LCD) with two bidirectional alignment layers using a stamping‐assisted rubbing process. The bidirectionally rubbed alignment layer through a stamping and peel‐off process provides the multi‐domain alignment of the LC molecules. The patterned fluorinated acrylate polymer, used as a protective layer, was produced to cover the rubbed alignment layer during the second rubbing process for the bidirectional LC alignment. Our multi‐domain TN‐LCD shows wide‐viewing characteristics that are symmetric with respect to the rubbing directions.
