Abstract
The present invention provides a display panel and a manufacturing method thereof. The display panel includes an array substrate, a pixel definition layer, and an organic light emitting device. The pixel definition layer includes a first definition layer and a second definition layer laminated together. The first definition layer includes a first aperture. The second definition layer includes a second aperture corresponding to the first aperture. The organic light emitting device is disposed in the first aperture. area of the top surface of the first definition layer is different from an area of the bottom surface of the second definition layer such that at least a part of a side surface of the first definition layer and a side surface of the second definition layer are in different planes.
