We demonstrate a Holographic‐Polymer Dispersed Liquid Crystal (H‐PDLC) with an enhanced viewing‐angle, formed by writing a diffuse hologram structure directly into our H‐PDLC material. We model the diffuse H‐PDLC reflectance by summing over the contributions of discrete grating domains of differing orientations. We use a normal distribution function to weight each orientation to describe the grating densities. SEM studies were performed to determine the morphologies and orientations of multiple gratings within the sample.
