<p>A packaging cover plate (100) for an organic electroluminescent device, an organic electroluminescent device and a display. The packaging cover plate (100) for an organic electroluminescent device is provided with a packaging surface (101) which is used for adhering to a substrate (200) via a packaging adhesive, and a groove structure (102) used for accommodating the packaging adhesive is formed on the periphery of the packaging surface (101) of the packaging cover plate (100). By arranging the groove structure (102) on the packaging surface (101) of the packaging cover plate (100), when the packaging cover plate (100) is adopted to package an OLED device, the packaging adhesive used for adhering the packaging cover plate (100) to the substrate (200) can be filled in the groove structure (102) of the packaging cover plate (100), so that the gap between the packaging cover plate (100) and the substrate (200) can be substantially reduced, thereby reducing water vapour penetration paths, improving the packaging effect of the OLED device, and prolonging the service life of the OLED device.</p> |
