An electro-optic device includes a liquid crystal cell ( 10, 10' ) and at least one electrode ( 40, 42, 40', 42' ) arranged to selectively electrically bias the liquid crystal cell ( 10, 10' ). A chiral or cholesteric liquid crystal ( 30, 30' ) is disposed in the liquid crystal cell ( 10, 10' ). The liquid crystal ( 10, 10' ) has an optic axis substantially along a selected optic axis direction in the absence of an electrical bias. A polymeric network ( 32, 32', 72 ) is disposed at an inside surface of the liquid crystal cell ( 10, 10' ). The polymeric network ( 32, 32', 72 ) extends partway into the liquid crystal cell ( 10, 10' ) leaving at least a portion of the liquid crystal cell ( 10, 10' ) substantially free of the polymeric network ( 32, 32', 72 ).
