Abstract For the first time we report direct measurements on asymmetric pretilt angles of OCB cell (pi‐cell) with results in good agreement with the pretilt angles measured on accompanying tilted homogenous cells fabricated by using same material and processing steps. Our method has potential applications to monitor the changing in pretilt angles of fresh made or aged pi‐cells.
