Abstract

Abstract : A simple process for a reactive mesogen (RM) alignment layer is demonstrated with potential wide spread application in liquid crystal devices. A low concentration (0.3% wt) of RM dissolved in a liquid crystal is aligned by an azodye layer. After polymerization of the RM, the azodye is "bleached" to remove its visible absorption. The result is a versatile, low cost, stable alignment layer that is practical for AMLCDs.
