Paper Abstract

The presence of hysteresis in transmittance-voltage characteristics of liquid crystal mixed with polymer (LCMP) has been the main cause for the residual image of LCMP display devices. This hysteresis is regarded to originate in the interaction between liquid crystal material and matrix polymer. The molecular motion of the matrix polymer of LCMP is varied systematically by changing the monomer and photo-initiator content. The hysteresis of LCMP decreases as the elastic modulus of matrix polymer decreases. It has been found quite effective to lower the elastic modulus of matrix polymer in reducing the hysteresis of LCMP.
