Organic electroluminescent display panel and manufacturing method thereof, and display apparatus

The invention discloses an organic electroluminescent display panel and a manufacturing method thereof, and a display apparatus. According to the organic electroluminescence display panel, a first groove for accommodating an organic electroluminescent structure is formed in a display area of a packaging cover plate; and at least one second groove encircling the first groove is formed in a non-display area of the packaging cover plate, wherein the boundary of the second groove is closed. A metal layer enables a protruding part of the packaging cover plate to be bonded with a substrate. Because the protruding part of the packaging cover plate and the metal layer located between the protruding part and the substrate have high molecular densities, a high-efficiency water and oxygen blocking effect can be realized. Moreover, frame sealing glue is accommodated by the second groove and the substrate and the packaging cover plate can be bonded well based on cooperation of the frame sealing glue. Therefore, the packaging cover plate and the substrate can be bonded well based on the metal layer and the frame sealing glue. And under the circumstances the bonding between the packaging cover plate and the substrate is guaranteed, the sealing performance of the organic electroluminescent display panel can be effectively improved.
