    Abstract: The present invention discloses an organic electroluminescent display element, an optical thin film laminate and a production method thereof. The optical thin film laminate comprises a circular polarizer film layer, a protection film layer provided on the light incidence side of the circular polarizer film layer, an adhesive layer provided on the light output side of the circular polarizer film layer, and a moisture and oxygen resistant film layer; wherein the moisture and oxygen resistant film layer is provided between the light output side of the circular polarizer film layer and the adhesive layer, and/or, between the light incidence side of the circular polarizer film layer and the protection film layer. Because the optical thin film laminate comprises the circular polarizer film layer and the moisture and oxygen resistant film layer, it may have both anti-reflection function and good moisture and oxygen resistant performance. When such dual functional optical thin film laminate is applied to OLED element, it may not only solve the problems of complicated process, increased cost, and the difficulty in rolling the flexible OLED element caused by duple film adhering; but also bring advantages such as more lightweighting and thinness, better display effect, and the like to the OLED element.

    Abstract translation: 本发明公开了一种有机电致发光显示元件，光学薄膜层叠体及其制造方法。 光学薄膜层叠体包括圆偏光膜层，设置在圆偏光膜层的光入射侧的保护膜层，设置在圆偏光膜层的光输出侧的粘合层，以及水分和氧气 耐热膜层; 其中，所述耐湿氧膜层设置在所述圆偏光膜层的光输出侧与所述粘合层之间，和/或所述圆偏光膜层的光入射侧与所述保护膜层之间。 由于光学薄膜层压体包含圆形偏光膜层和防潮和耐氧膜层，所以它具有抗反射功能和良好的耐湿和耐氧性能。 当将这种双重功能的光学薄膜层压体应用于OLED元件时，不仅可以解决复杂工艺，增加成本以及由双面胶粘附引起的柔性OLED元件的滚动困难的问题; 而且还具有对OLED元件更多的轻量化，薄型化，更好的显示效果等优点。
