The placement of the liquid crystals between two surfaces that are smooth grooves. Smooth grooves on the surface make an angle of 90o a (perpendicular) with smooth grooves on the other surface. If the molecules are arranged in an area of north-south and a molecule on the surface directed from west to east, there are molecules of which will be required to rotate 90o. As a result, the path of light that followed the structure of this molecule also rotates 90° when passing through the liquid crystal. When the electricity voltage supplied to the liquid crystal, the molecules are arranged vertically allows light to pass through without turning 90o. b. Based on the polarization properties (is a collection of thin, parallel lines). Through this polarizing filter, the light from background sources is filtered and, then, rotated by the liquid crystals and is filtered again before leaving..
