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.
