POLARIZING ELEMENT AND POLARIZING PLATE FOR DISPLAY DEVICE HAVING BLUE LIGHT EMITTING ELEMENT |
摘要 |
[Problem] The present invention relates to a polarizing element and a polarizing plate, which can improve contrast and enhance color display characteristics in an organic electroluminescent display device. [Solution] A substrate having a polarizing function and containing an azo compound is controlled such that the substrate alone has a transmittance of 45% to 60%, the average transmittance of 440-nm to 500-nm wavelengths for one substrate is 50% or more, and the average transmittance of 550-nm to 650-nm wavelengths as obtained by measuring two substrates arranged such that the absorption axis directions thereof are orthogonal to one another is 10% or less. |
