The specification describes a liquid crystal panel for a twisted nematic liquid crystal that provides the best angle of view in a normal direction to the plane of a glass substrate. Each liquid crystal cell representing a pixel is divided up into two domains, a positive tilt and negative tilt domain. The relationship of the positive tilt and negative tilt domains is equalized in order to orient the molecules in the middle of the cross section of a cell with the desired neutral tilt. The positive and negative tilts are produced by the process of adding a chiral dopant to the liquid crystal, or by a bias-rubbing process, or a combination of both processes. A further characteristic of the panel is that angle of view is symmetric in the vertical
