摘要： A display panel integrated with EL can be obtained by printing EL at the back of a light permeable substrate, and covering the front surface of the substrate and the rearface of EL with a moisture proof film for insulating and protecting the EL from the surrounding atmosphere. Alternatively, the film may cover the substrate and EL entirely. An indication mark is printed at the surface of the moisture proof film or the light permeable substrate. The light permeable front electrode, the light emission layer and the back electrode are successively printed to the rearface of the light permeable substrate. If the indication mark is printed on the surface of the substrate, the attenuation of decay of the light emission from the emission layer can be suppressed and the brightness of the display mark improved by not forming the insulation layer at the back of the substrate. Alternatively, by forming the insulation layer at the back of the substrate, the entire thickness and the weight of the display panel can be decreased and the production step simplified.
摘要翻译：与EL集成的显示面板可以通过在透光性基板的背面进行EL印刷而获得，并且用防潮膜覆盖基板的前表面和EL的背面，用于绝缘并保护EL免受周围环境的影响。或者，膜可以完全覆盖基板和EL。在防潮膜或透光性基材的表面印刷指示标记。透光性前电极，发光层和背面电极依次印刷到透光性基板的背面。如果指示标记被印刷在基板的表面上，则能够抑制来自发光层的发光衰减的衰减，并且通过在基板的背面不形成绝缘层来提高显示标记的亮度。或者，通过在基板的背面形成绝缘层，可以减小显示面板的整体厚度和重量，简化制作工序。
