The refraction of an extraordinary light wave in a layer of a chiral liquid crystal with the director rotated 90$^\circ$ has been studied. In this structure, if a light wave is incident on the surface of the liquid crystal at a large angle and the light passes through the whole layer, it refracts at the opposite boundary of the layer. The angular dependence of the light transmission through the liquid crystal layer has been researched. It has been demonstrated that the electric field changed the character of the refraction of the extraordinary wave and the light started to pass through the layer. The threshold voltage of the light transmission has been determined, as well as its dependence on the light incidence angle. The effect dynamics have been studied and the angular dependence of the light transmission decay time has been determined.
Keywords: chiral liquid crystal, relaxation time.
