A simple technique for achieving dual-domain alignment in a twisted nematic liquid crystal display (TN-LCD) is proposed. By incorporating the use of linearly polarized deep UV (DUV) for liquid crystal alignment, only one rubbing and one photolithographic process are added to conventional TN fabrication. We fabricated dual-domain twisted nematic (DDTN) cells using this technique with a practical pixel resolution. This DDTN cell has very symmetrical viewing characteristics in both the vertical and horizontal viewing directions. With the use of the proper type of retardation films along with this DDTN we have been able to achieve a contrast ratio of 10:1, to almost ±40° in the vertical and beyond ±60° in the horizontal viewing directions, without any gray-scale inversion.
