2.  Introduction
 Basic Theory of Liquid Crystals
 Classification of Liquid Crystals
 Description of Liquid Crystals
 Applications of Liquid Crystals

3. Liquid Crystals (LC) – matter in a state that has properties between
those of conventional liquid and those of the solid crystals

5. Nematic Liquid Crystals
– No translational order
– Least ordered mesophase
Smectic Liquid Crystals
– Liquid like motion of the rods in each layer
– Layers can easily slide
– No correlation of the molecular positions from one
layer to the next.
