The technical scheme of the invention provides a display panel and a manufacturing method thereof. The manufacturing method comprises the following steps: providing a substrate; forming an auxiliary structure in a first preset area, corresponding to the blind hole area, of the substrate; a pixel circuit and a light-emitting element connected with the pixel circuit are formed in a second preset area, corresponding to the display area, of the substrate, the light-emitting element comprises a common layer and a cathode layer located on the side, away from the substrate, of the common layer, and the common layer and the cathode layer both extend to the position above the auxiliary structure from the second preset area; in the first preset area, based on the auxiliary structure, a first film layer structure on the side, away from the substrate, of the auxiliary structure is removed, and the first film layer structure at least comprises a common layer and a cathode. According to the technical scheme, the influence on the light transmittance due to the fact that the blind hole area is provided with the first film layer structure can be solved, and the lighting performance of the blind hole area is improved.
Description
technical field [0001] The present application relates to the technical field of display panels, and more particularly, to a display panel and a manufacturing method thereof. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display function are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable part of today's people. important tool that is missing. An important structure for realizing the display function of an electronic device is a display panel. [0003] In order to integrate more functions in an electronic device, blind holes need to be arranged in the display panel, so as to integrate under-screen electronic components, such as cameras or other optical components, below the corresponding blind hole area of the display panel. In the related art, the light transmittance of the blind hole area is low, w...
