In this study, the photolithographic technique for molecular alignment on
the polyimide thin film was studied. The liquid crystal alignment properties of the photolithographic
application were presented by the polyimide thin films and observed on
photoaligned polyimide film by a surface profiler. This method was provided by the micropatterning
process that includes spin-coating, UV exposing and wet chemical etching. The
cell gap of liquid crystal displays was measured by the rotational scanning interferometer
unit. The results of the photolithographic method and the molecular alignment properties
of the nematic liquid crystal cell were observed by applying an electric field with the
micro-patterning interval of approximately 100 microns. These results will be developed
gradually in further studies for nano-scale applications.
