In this paper, we propose a new reflective LC phase modulator design by combining the advantage of the polymer wall to reduce the fringe field and an incorporated QWP to make the device polarization independent. This new design has promising application in the projection system, since the resolution and brightness of current LCoS projector will be limited by the fringe field and diffraction effect, while this new design is utilizing the diffraction effect and immune to the fringe field effect. We fabricate a diffractive cell, and the experiment result shows the device is polarization independent and yields high diffraction efficiency.
