Abstract

The invention relates to a plastic liquid crystal film which comprises a liquid crystal-plastic core layer and two transparent conductive films, wherein the transparent conductive films are parallel and are arranged symmetrically, the liquid crystal-plastic core layer is clamped between the two transparent conductive films and comprises a high molecular polymer substrate, micro balls made of a liquid crystal material are uniformly distributed in the high molecular polymer substrate, the refractive index of the high molecular polymer substrate is matched with the refractive index of ordinary light of the liquid crystal material, liquid crystal molecule directors in the micro balls made of the liquid crystal material are approximately parallel to the two transparent conductive films, and electrodes are arranged on the transparent conductive films. The plastic liquid crystal film has the characteristic of high scattering degree during power off, and the gray level of the plastic liquid crystal film can be adjusted when the voltage of an external electric field is between a threshold voltage and a saturation voltage.
