Abstract

Herein we demonstrate the improved performance of electrically controlled birefringence (ECB) cells fabricated on solution-derived La₂O₃ films pre-treated with ion beam irradiation. Treatment by an ion-beam (IB) irradiation system and appropriate annealing temperature allowed La₂O₃ surfaces to support homogeneous liquid crystal (LC) alignment. The EO characteristics of the aligned homogenous LCs and ECB modes in cells fabricated on La₂O₃ layers were comparable to those of cells fabricated on polyimide, and IB-irradiated La₂O₃ film surfaces showed good potential for use as an alignment layer.
