ABSTRACT:
The orientation of the alignment layer in a raster-scanned thermally addressed smectic liquid crystal display device can be chosen relative to the writing orientation to accentuate a selected characteristic. A perpendicular alignment with respect to the scan direction produces uniformly written images in both scan directions to allow high quality bidirectional writing. In a preferred embodiment the liquid crystal cell includes a liquid crystal material comprising 4-octyloxy-4'-cyanobiphenyl 37.5%, 4-decyl-4'-cyanobiphenyl 36.8% weight percent and 4-undecyl-4'-cyanobiphenyl 25.7 weight percent.
