Abstract

The embodiment of the invention provides a display panel, a preparation method thereof and a display device. In the display panel provided by the embodiment of the invention, modification layers are arranged on the sides, away from a substrate, of graphic structures and the sides, exposed out of the graphic structures, of the substrate, the modification layers comprise a plurality of fold structures, and the height difference between the protrusion and the adjacent groove in any fold structure in the first area is smaller than the maximum segment difference between the graphic structures on the two sides of the first area and the surface of one side of the substrate, and therefore the segment difference in the first area of the display panel can be effectively reduced through the fold structures, the fold structures can effectively support a flat layer, and the display effect is improved. Therefore, the concave degree of the flat layer in the first area can be reduced, the flat effect of the flat layer is enhanced, and the working stability of the display panel can be guaranteed.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, display panels are widely used in various terminal products. Existing display panels include device structures such as multiple transistor structures, light-emitting structures, and photoelectric sensing elements. The above-mentioned device structures all include multiple graphic structures. stacked state. Moreover, in different regions of the display panel, the overlapping situations of the graphic structures are different, resulting in different thicknesses in different regions of the display panel. [0003] In the prior art, the graphics structure is mainly processed through a planarization process, and a flat layer is formed on the side of the graphics structure away from the substrat...
