Abstract: Provided is a display panel comprising an anode layer, a sacrificial layer disposed on an anode layer, a pixel definition layer covering the sacrificial layer and the anode layer, and a light-emitting functional layer disposed in the groove and the light-emitting area opening, and a manufacturing method thereof, wherein the sacrificial layer is formed with a groove at a position corresponding to the light-emitting area opening. In this way, the sacrificial layer forming at the light-emitting area opening can be removed to form a groove at the same time in the process of forming the light-emitting area opening by exposure and development, so that it is possible to ensure that no pixel definition layer remains on the anode layer at the light-emitting area opening, thereby solving the problem that the light-emitting functional layer cannot be spread.
