The fully leaky waveguide measurement system has been set up to measure the reflective mixed-mode twisted nematic liquid crystal cell.He-Ne laser was processed to become s polarized light or p polarized light.The polarized lightenters the liquid crystal cell by prism-coupled method and then the reflective signals with the combination of different polarized light that depend on the incident angle were collected under different voltages. The reflective light in different state can be predicted by means of simulation which was based on multilayer optical 44 matrix and elastic continuum theory. Tilt angle
twist angle and distribution of the director in liquid crystal cell under different voltage can be obtained by fitting the experiment data.
