Color shift on off-axis angles is key issue of the cholesteric liquid crystal (CLC) polarizer. In this paper, color shift issues
on various azimuthal and viewing angles of back light unit assembled with CLC polarizers are analyzed by optical
simulation. We found that smaller NZ value of quarter-wave plate (QWP) of our samples will compensate the color shift
issue more efficiently. Although abnormal dispersion type QWP gives the best performance at the on-axis viewing
angles, at large viewing angle its color shift is depending on azimuthal angle and bandwidth of CLC polarizers. Besides,
a single layer type CLC polarizer of gradient pitch over a shorter bandwidth has better color coordinate property also be
performed.
