Liquid crystalline electrooptical device
First Claim
1. An electrooptical light modulating device comprisinga liquid crystalline material disposed between first and second opposing cell wall structures and comprising liquid crystal of positive dielectric anisotropy,wherein said first cell wall structure is treated with a first aligning material to homeotropically align liquid crystal molecules of the material and said second cell wall structure is treated with a second aligning material that is different from said first aligning material to homeotropically align liquid crystal molecules of the material, whereby said liquid crystal exhibits a unipolar electrooptic effect in the presence of an electric field.

Abstract
An electrooptical light modulating device includes a liquid crystalline material disposed between first and second opposing cell wall structures and comprising liquid crystal of positive dielectric anisotropy. The first cell wall structure is treated with a first aligning material to homeotropically align liquid crystal molecules of the material and the second cell wall structure is treated with a second aligning material that is different from the first aligning material to homeotropically align liquid crystal molecules of the material, whereby the liquid crystal exhibits a unipolar electrooptic effect in the presence of an electric field.
