Abstract

Polymer dispersed liquid crystal(PDLC) light shutters are scattering in the OFF state and transparent in the ON state for normally incident light. PDLC shutters appear hazy in the ON state when viewed at oblique angles as a result of light scattering. The haze is caused by the effective increase in the refractive index of the liquid crystal. However, only one polarization of the incident radiation is scattered. Therefore, PDLC shutters with a linearly polarized sheet on the incident surface are haze‐free for an entire viewing plane. While addition of a polarizer reduces transmission through the PDLC to less than 50%, it also offers a simple means of producing haze‐free PDLC shutters for applications where viewing is predominantly in one plane.
