Geometry and characterization.
(a) Sketch of the geometry of a hybrid-aligned cell. (b) Sketch of the geometry of a homeotropic-aligned cell. (c) Photograph of a hybrid-aligned cell. (d) Photograph of a homeotropic-aligned cell. (e) Polarized optical micrograph of a hybrid-aligned cell on a rotatable stage. (f) Polarized optical micrograph of a homeotropic-aligned cell on a rotatable stage. Optically transparent film with hybrid alignment is confirmed from photograph and conoscopic images with a polarized optical microscope.
