Abstract

A particularly simple four-domain (4-D) twisted nematic (TN) liquid crystal display (LCD) device is proposed, which is composed of two left-handed TN and two right-handed TN subpixels. One of each pair of same handedness subpixels is rotated 180 degrees with respect to the other, resulting in four domains that spatially average one another optically to provide a wide angle of viewing with no gray scale inversion. The detailed fabrication process is presented for a two step SiOx oblique evaporation technique used to realize this 4-D TN LCD. A reverse rubbed polyamide fabrication process has also been successfully used and will be presented in the full length article. Here we present the complete viewing angle and contrast ratio data for a simple and successful 4-D TN LCD cell. (C) 1995 American Institute of Physics.
