US Patent 7593082 - CNT/Polyimide alignment material

This patent from LG Display teaches mixtures of CNT and polyimide to facilitate alignment of LCD materials. Claim 1 reads:

1. An alignment material for a liquid crystal display (LCD) device, comprising a mixture of carbon nano-tube and polyimide.

An example of uncited prior art which appears relevant is the article "Liquid crystal-carbon nanotube dispersions" published in the Journal of Applied Physics on 25 January 2005 which teaches using a rubbed polyimide alignment layer in a CNT-liquid crystal dispersion.
