摘要： As for the dual emission display device, since light is emitted to the opposite directions from a light emitting element, the both electrodes provided opposite to the light emitting element are transparent/ translucent. Accordingly, difficulty in black display is created, and thus, the contrast would be reduced. That results from that the back of the display device can be seen through in black display, that is in the OFF state, since the both electrodes have transparency. Addressing the difficulty in black display with respect to an electronic device and the like including a dual emission display device achieving reduction in the thickness and light weighting, pure black display is performed by providing the dual emission display device part with a polarizing plate or a circularly polarizing plate. Further, the contrast can be improved.
摘要翻译： 对于双发射型显示装置，由于光从发光元件向相反方向发射，所以与发光元件相对设置的两个电极是透明/半透明的。 因此，产生了黑色显示的困难，因此对比度会降低。 这是由于显示装置的背面可以通过黑色显示器看到，即处于OFF状态，因为两个电极都具有透明度。 针对包括实现厚度和重量减轻的双发射型显示装置的电子装置等解决黑色显示的困难，纯黑色显示通过给双发射型显示装置部件提供偏振片或圆形 偏光板。 此外，可以改善对比度。
