Optimal design of quarter-wave plate with wideband and wide viewing angle for three-dimensional liquid crystal display

In this paper, we propose an optical structure for a circular polarizer-containing film patterned retarder (FPR), which has wideband and wide-view properties in a stereoscopic three-dimensional (3D) display. The FPR consists of a patterned λ/4 A-plate, a biaxial λ/2 plate, and a positive C-plate. We calculate the phase retardation of each film in the entire visible wavelength with the Stokes vector and the Muller matrix method. We demonstrate the excellent 3D characteristics of the proposed polarizer in the oblique direction by comparing the calculated light leakage of the proposed optical configuration with that of the conventional configuration. We calculate that the crosstalk of the proposed configuration is reduced to 0.39 for the left image and 0.29 for the right image in the horizontal oblique direction and to 0.37 for the left image and 0.29 for the right image in the vertical oblique direction (polar angle 70°). These results indicate that the proposed configuration improves crosstalk by approximately 90 compared to the conventional mode.
