    Abstract: An organic electroluminescence device includes: a substrate; a switching layer disposed on the substrate, and the switching layer includes multiple switching elements arranged as a matrix; an organic electroluminescence layer disposed on the switching layer, the organic electroluminescence layer includes multiple organic electroluminescence elements arranged as a matrix, the organic electroluminescence elements are controlled to emit light through corresponding switching elements; a first planarization layer disposed on the substrate, covering on the switching layer and the organic electroluminescence layer; and a touch layer disposed on the substrate and covering on the first planarization layer. The present invention also provides a manufacturing method for the organic electroluminescence device. Using the first planarization layer to directly encapsulate the switching layer and the organic electroluminescence layer, and no additional Thin Film Encapsulation layer is required. Accordingly, the thickness of the production is reduced and the cost is saved at the same time.

    Abstract: The OLED display of the invention comprises a TFE layer, comprising: inorganic passivation layers, organic buffer layers and a moisture/oxygen quenching layer (MOQL), wherein the inorganic passivation layers and the organic buffer layers form a stacked structure, and the MOQL comprises a first MOQL located between the stack structure and OLED layer, or a second MOQL located between the two inorganic passivation layers, or a combination of two. In TFE layer, the MOQL can effectively prevent, through physisorption or chemical reaction, the damage of the OLED device caused by moisture/oxygen without affecting the luminescence performance of the OLED device so as to enhance the OLED device lifespan, and release the stress of inorganic passivation layers in TFE layer, reduce the number of layers and thickness of the TFE layer, thereby reduce the thickness of the OLED display and improve the flexibility of flexible OLED display.
