ABSTRACT:
A liquid crystal apparatus including a low birefringence encapsulated liquid crystal material in a containment medium. The difference between the ordinary index of refraction and extraordinary index of refraction of the liquid crystal material is between about 0.050 and 0.115. The index of refraction of the containment is greater than the ordinary index of refraction of the liquid crystal material. The liquid crystal apparatus provides low haze at off-axis viewing angles and permits efficient sine-wave power operation.
