Broadband retarder BBR, keeping away from crosstalk between the binocular parallax images, is the key component of the polarization based 3D stereoscopic display system. In case of rotating the viewer's polarization glasses, circular polarization light is needed for preserving stereo perception. Eliminating wavelength depended optical properties is the goal for BBR design. BBR has been widely applied for LCD display. However, the previous studies did not meet the rotating analyzer and in those cases did not have compensated retarder. Since the analyzer rotates, retardationwavelength relationship is failed to represent both the transmittancewavelength property and the color performance. In this paper, we use a numerical solution rather than an analytical solution to analyze dispersive issues. The transmittance, crosstalk and color shift metrics are used to evaluate the BBR quality, and 25% crosstalk, 33.73% red color shift and 26.4% green color shift problems are improved in our design.
