CIRCULAR POLARIZING PLATE AND ORGANIC ELECTROLUMINESCENCE PANEL |
摘要 |
<p>There is provided a circularly polarizing plate that can prevent light leakage in an organic EL panel and can suppress the warping of the panel to reduce reflection unevenness in a panel surface. A circularly polarizing plate according to an embodiment of the present invention is used in an organic EL panel, and includes a polarizer and a retardation film directly bonded to the polarizer. In-plane retardations of the retardation film satisfy a relationship of Re(450)<Re(550); and a 90° adhesive strength between the polarizer and the retardation film is 1.0 N/20 mm or more.</p> |
