    Abstract: [Problem] To provide a highly-transmissive polarization plate that can express achromatic white when a polarization element is arranged parallel to an absorbing axis, and achromatic black when the polarization element is arranged orthogonal to the absorbing axis.[Solution] A single body, which is a base material that contains a dichromatic dye formed from an azo compound, that exhibits transmissivity of equal to or greater than 35% and a polarization degree adjusted to equal to or greater than 99% and is characterized in that a* and b* values, which are acquired for a polarization element or a polarization plate using JIS•Z•8729, have an a* and b* absolute value that is: less than 1 at the time of a single-body transmittance measurement; less than 2 when two sheets of the base material are arranged parallel to the absorbing axis direction and the a* and b* values are measured; and less than 2 when two sheets of the base material are arranged orthogonal to the absorbing axis direction and the a* and b* values are measured.

    Abstract: [Problem] To provide a highly-transmissive polarization plate that can express achromatic white when a polarization element is arranged parallel to an absorbing axis, and achromatic black when the polarization element is arranged orthogonal to the absorbing axis.[Solution] A polarization element, which is obtained from a base material containing a dichromatic dye formed from an azo compound, is characterized in that the single-body transmittance is 35-60%, and a* and b* values, which are acquired for a polarization element or a polarization plate using JIS•Z•8729, have an a* and b* absolute value that is: less than 1 in a single-body transmittance measurement; less than 2 when two sheets of the base material are arranged parallel to the absorbing axis direction and the a* and b* values are measured; and less than 2 when two sheets of the base material are arranged orthogonal to the absorbing axis direction and the a* and b* values are measured.
