Abstract
Experimental observations show that the nematic order parameter is signi cantly enhanced as the thickness of the cell is reduced. Calculations of earlier theories do not agree well with the experimental data. We propose a simple extension of Maier Saupe theory to account for the enhancement. A molecule near the surface is assumed to feel the mean eld potential (the Maier Saupe type) and also the surface induced potential. This is included in the Maier Saupe theory. Our calculations are in better agreement with the experimental data.
