Claim Text:
1. A stereoscopic image display device, an image emitted from which is observed with wearing polarizing glasses comprising a region for a right eye and a region for a left eye, each region comprising a retardation layer and a polarizer, the device comprising: a display part configured to generate an image signal; and a filter part comprising a first region and a second region, which are configured to divide the image signal from the display part into at least two signals having different polarizing states from each other, each region comprising a retardation layer, wherein a crosstalk ratio measured during observing the image signal with wearing the polarizing glasses is 6% or less, an X value and a Y value of a tristimulus value of CIE color space of the image signal in a bright state are in the range from 0.322 to 0.344 and from 0.316 to 0.350, respectively, and an X value and a Y value of a tristimulus value of CIE color space of the image signal in a dark state are in the range from 0.223 to 0.443 and from 0.078 to 0.589, respectively, wherein the retardation layers of the regions for right and left eyes of the polarizing glasses and the retardation layers in the first and second regions of the filter part satisfy the General Formula 1 or 2: wherein D
