Abstract
Cross talk between left and right images on a 3D display deteriorates the picture quality severely. This paper describes qualitatively how the cross talk occurs and shows some experimental results. In a projection type display, a rear screen and a mirror affect the polarization. Strain on manufacturing process causes double refraction in screen. Due to the double refraction, when the incident light is linear polarized one the output is elliptically polarized light and cross talk occurs. A mirror has a complex refractive index and when linear polarized light is reflected, the output is elliptically polarized light, producing cross talk.
