LCD basic display theory. When an electrical field is applied to the LC planes, the LC molecules re-align themselves so that they are parallel to the electrical field. This electrical process is known as twisted nematic field effect or TNFE. In this alignment, polarized light is not twisted as it passes through the LC material (see Diagram 3A and 3B).
