Abstract
A liquid crystal injection apparatus and method for injecting a liquid crystal material between substrates of a liquid crystal display panel. The method and apparatus includes using an electric field to orientate the liquid crystal material during injection such that the liquid crystal material has a reduced viscosity. The electric field can be produced by electrodes adjacent the substrates, and by an electric source that applies a potential to the electrodes. Liquid crystal material injection can be the result of capillary forces and/or differential pressure.
