The present invention provides an OLED element, a substrate (1), an OLED thin film element (2), being positioned on the substrate (1), an organic package thin film (3), being positioned on the substrate (1) and completely covering the OLED thin film element (2), an inorganic package thin film (4), being positioned on the substrate (1) and completely covering the organic package thin film (3), a protective cover (5) sealing the peripheric edges of the substrate (1) and mantling on the inorganic package thin film (4) and a rigid support plate (6) positioned at a side of the protective cover (5) away from the substrate (1). The OLED element of the present invention possesses the better mechanical property and is hard to be damaged by an external force. Meanwhile, the better airtightness protection can be provided to the OLED thin film element.
