Liquid Crystals and DC Fields

This is a slice of a liquid crystal display. The gray rectangles are "electrodes" that you can turn on and off by clicking on them. When they are on, their "field" is shown in green.

The blue box is a macro view of one of the molecules...the one marked by a red circle. You can choose other molecules by clicking on them. You can also drag the selected molecule around to see how its position affects its orientation.
