Domain walls in photoaligned double‐domain twisted‐nematic LCDs

Abstract— Advanced two‐ and three‐dimensional modelling was used to explain microscopic measurements on two different double‐domain twisted‐nematic liquid‐crystal‐display (TN‐LCD) configurations that were made using photoalignment. The shape of domain walls and their effect on the transmitted intensity were described correctly. For some double‐domain configurations, the brightness and contrast of the display will be affected by the domain walls.
