Abstract
Liquid-crystal displays based on an induced twist in a nematic liquid often have a patched appearance when viewed at nonnormal incidence. This fault has previously been unexplained. It is shown by experiment that the patches reveal regions of reverse twist relative to that in neighbouring areas.
