Abstract
Two-dimensionally self-organized smectic liquid crystal (LC)-polymer composite has been reported to show a negative dispersion of birefringence [H. Lee and J.-H. Lee, Opt. Lett. 39, 5146 (2014)]. In this paper, we separately measured the extraordinary and ordinary refractive indices ninfe/inf and ninfo/inf of the pure LC and LC-polymer composite and simulated the dependence of the transmittance and the color on the viewing angle for the display application. The LC-polymer composite with the negative dispersion property showed a wider viewing angle and a smaller color shift compared to the pure liquid crystal with a positive dispersion of birefringence.
