The invention discloses a display panel manufacturing method and a display panel. The embodiment of the invention provides a manufacturing method of a display panel, and the method comprises the steps: providing an array substrate which is provided with a first region and a second region; a first electrode layer used for hole injection is formed on the array substrate, a pixel definition layer with a pixel opening and a sacrificial layer with a two-dimensional pattern are formed on the first electrode layer, and the pattern of the sacrificial layer covers the first area; a second electrode layer is formed on the sacrificial layer and the organic light-emitting layer, and light emitted from the organic light-emitting material can penetrate through the second electrode layer; and patterning the second electrode layer corresponding to the first region by taking the two-dimensional pattern of the sacrificial layer as a template so as to form a patterned cathode complementary with the two-dimensional pattern. According to the manufacturing method of the display panel provided by the embodiment of the invention, the organic light-emitting layer can be protected from being damaged by laser in the subsequent etching process.
Description
technical field [0001] The invention relates to the display field, in particular to a method for manufacturing a display panel and the display panel. Background technique [0002] With the development of mobile phones and other consumer electronics products including display panels and cameras, people have higher requirements for the visual experience of these electronic products, and users have higher and higher requirements for screen ratio, making the full screen of electronic devices The display has received more and more attention from the industry. [0003] Traditional electronic devices, such as mobile phones and tablet computers, need to integrate front-facing cameras, earpieces, and infrared sensing elements. Traditional devices set a light-transmitting area on the display screen, and external light can enter the photosensitive element located below the screen through the light-transmitting area on the screen. However, due to the existence of the light-transmittin...
