CIRCULAR POLARIZING PLATE AND BENDABLE DISPLAY DEVICE |
| 摘要 |
<p>PROBLEM TO BE SOLVED: To provide a circular polarizing plate that can achieve a bendable display device giving a superior reflectance hue and suppressing changes in colors resulting from bending.SOLUTION: The circular polarizing plate is used in a bendable display device. The circular polarizing plate includes a polarizer and a retardation film disposed at one side of the polarizer. The in-plane retardation of the retardation film satisfies the relationship of Re(450)<Re(550)<Re(650). The slow axis direction of the retardation film is adjusted in a manner so as to prescribe an angle from 20° to 70° with respect to the bending direction of the display device.</p> |
