Abstract

The invention discloses a display panel and a manufacturing method of the display panel, and the method comprises providing a substrate, and sequentially forming display structure layers on the substrate, wherein the display structure layers are provided with at least one alignment mark; forming light-transmitting parts on the sides away from the substrate on the display structure layers, whereinthe light-transmitting parts covers the alignment marks one-to-one; coating black material layers on the entire surfaces of the display structure layers away from the substrate, wherein the light-transmitting parts make the alignment marks recognizable; carrying out alignment through the alignment marks, and patterning the black material layers to form a black light-shielding layer. The embodimentof the invention provides a manufacturing method of the display panel. Before the black light-shielding layer is formed, the light-transmitting parts of the alignment marks are made to realize recognizable areas of the alignment marks, thereby enabling precise alignment of the black light-shielding layer in the process of patterning to form a black light-shielding layer with precise position, which is simple and practical.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] With the development of full-screen applications, the utilization rate of the front of the display screen is required to be higher and higher. Among them, the space of the camera module part has always been what everyone hopes to use. In order to make good use of the space in this part of the camera, it is necessary to hide the camera here under the display. In order to realize the shooting technology of the camera under the screen, it is not only required to have a high transmittance of the front screen of the camera, but also to reduce the influence of ambient light and reflected light on the camera. Therefore, there is a problem of how to reduce the interference of ambient light and reflected light on the camera. . Contents of the invention [0003] For this reason, the present invention pr...
