REFLECTIVE POLARIZING FILM, OPTICAL MEMBER FOR LIQUID CRYSTAL DISPLAY DEVICE FORMED FROM SAME, AND LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
A multilayered reflective polarizing film is provided that has high polarization performance comparable to that of an absorption-type polarizing plate, and is preferred as a polarizing plate attached to a liquid crystal cell. An optical member for liquid crystal display devices, and a liquid crystal display device formed from such a multilayered reflective polarizing film are also provided. Specifically, the reflective polarizing film includes a uniaxially stretched multilayered film in which a specific aromatic polyester containing (alkylenedioxy)di-2-naphthoic acid as a part of dicarboxylic acid components is used as a first layer, and an optically isotropic polyester having an average refractive index of 1.50 to 1.60 is used as a second layer, and that has a predetermined refractive index difference between the layers. The reflective polarizing film has an angle of orientation of 2 degrees or less. |
