<p>An upper electrode plate (1) has a 0.15 to 0.8 mm thick optically isotropic heat-resistant transparent resin plate (8) having a glass transition temperature characteristic of not less than 150 DEG C. The heat-resistant transparent resin plate is laminated directly or indirectly on a quarter wave plate (9) all over their surfaces. <IMAGE></p> |
