ACHROMATIC POLARIZATION ELEMENT, AND POLARIZATION PLATE |
摘要 |
[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* and b* values, which define the hue of a polarization element or a polarization plate using JIS·Z·8729, are adjusted such that the absolute value of the a* and b* values is: less than 1 during a single-body transmittance measurement; less than 2 when two sheets of a 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. |
