Abstract
The present disclosure provides a display panel including a substrate, an anode on the substrate, a pixel defining layer on the anode, a light-emitting layer on the pixel defining layer, a first organic layer on the light-emitting layer and an inorganic layer on surfaces of the plurality of pixel walls in the pixel defining layer and the first organic layer. The pixel defining layer includes a plurality of pixel walls and pixel defining areas. The light-emitting layer is in the pixel defining areas and covering the anode. The first organic layer includes a plurality of first protrusions. The inorganic layer includes a plurality of second protrusions, the second protrusions are located on a side of the inorganic layer away from the first organic layer, and each of the second protrusions corresponds to each of the first protrusions. A display panel preparation method and a display device are further provided.
