Introduction to Liquid Crystals

The existence of liquid crystals has been known for nearly a centu­ ry; yet it is only in the last ten years that their unique optical, electri­ cal, electro-optic, and thermal properties have been exploited to any significant extent in such technological applications as digital d~­ plays and thermography. Digital watches equipped with liquid-crys­ tal displays (LCD''s) have recently made their de...
