Patent ID: 8848158

Claim:
A reverse mode liquid crystal display device, comprising: a first substantially transparent substrate having an electrically conductive material associated therewith; a second substrate having an electrically conductive material associated therewith; and a liquid crystal medium contained within a chamber positioned between the first substrate and the second substrate, the liquid crystal medium comprising: a nematic, negative dielectric anisotropic liquid crystal; and a macrocyclic compound, a borane, or a combination of any two or more thereof; wherein: the macrocyclic compound is represented as: X 1 -X 4 of the macrocyclic compound are individually O or N; R 1 -R 4 of the macrocyclic compound are individually H, C 1 -C 10 alkyl, C 1 -C 10 cycloalkyl, C 1 -C 10 heterocycloalkyl, C 1 -C 10 alkaryl, or C 1 -C 10 aryl, or where any of X 1 -X 4 is O, the corresponding R 1 -R 4 is absent; m of the macrocyclic compound is 1, 2, 3, 4, or 5; n of the macrocyclic compound is 1, 2, 3, 4, or 5; the borane is represented as: R 1 -R 4 of the borane are individually H, C 1 -C 10 alkyl, C 1 -C 10 cycloalkyl, C 1 -C 10 heterocycloalkyl, C 1 -C 10 alkaryl, or C 1 -C 10 aryl; m of the borane is an integer of 1 to 15, inclusive; and n of the borane is an integer of 1 to 15, inclusive.
