摘要 |
A polarizer that can be used for forming a liquid crystal display or an electroluminescent display with less display irregularities and excellent display characteristics is provided. The polarizer contains a dichroic material in a matrix, and its in-plane retardation at a measurement wavelength providing no absorption is in a range of 950 to 1350 nm. The measurement wavelength is preferably a wavelength that the dichroic material provides no absorption, and it is 1000 nm, for example. |
