Influence of Electric Field and Light on an Easy Axis of NLC Confined by Rectangular Channel at Weak Surface Anchoring

We present new experimental results on combined action of light and electric field on a nematic liquid crystal in a rectangular channel at a weak surface anchoring. The first experimental study of slow surface dynamics at combined action of electric field and polarized light in new experimental geometry was performed. Influence of polarized light on spatial twist-like deformation of a director field induced by electric field was established.
