Analysis of LC alignment fabricated in S1805. (a) Photos taken of the sample backlit with polarized light. Left: Light incident onto the uniformly rubbed surface. Middle and Right: Light incident onto the patterned surface, where recognizable features are clearly visible in separate aligned regions. (b) Original logotype used in the LC cell, and micrograph with a standard polarizer placed in parallel (P||) and crossed (P⊥). The blue lines indicate standard polarizer (P) direction, red line indicate the polyimide rubbing direction (RD) of the polyimide and yellow lines indicate the alignment angle (φ) patterns. (c) Grayscale pattern entropy (H) of LC cell in S1805 aligned patterned polarizer.
