Abstract

The embodiment of the invention provides a display panel, a manufacturing method thereof and a display device, the display panel comprises a display area and a peripheral area surrounding the display area, and the display panel comprises a substrate, a thin film transistor layer, a first planarization layer, a wiring layer, a second planarization layer and an anode metal layer which are stacked in sequence; the wiring layer is located in the display area, the first planarization layer and the second planarization layer extend from the display area to the peripheral area, and the anode metal layer comprises an anode layer located in the display area and an alignment mark located in the peripheral area. The two planarization layers are arranged in the display panel, the alignment mark is manufactured on the surface of the second planarization layer, the situation that when the alignment mark is manufactured on the first planarization layer, the alignment mark is not flat due to surface damage of the first planarization layer is avoided, the flatness of the alignment mark is guaranteed, and the display quality is improved. And the risk that the alignment mark becomes black and is difficult to identify is reduced.

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] Optical functional film (such as OCA optical glue, polarizer, etc.) is one of the important components of the display panel. Its filming efficiency and film orientation accuracy affect the performance of the display panel, as well as the production cost. [0003] In the production process of the display panel, when the optical functional film is attached to the display panel, it is necessary to perform the alignment through the alignment marks provided on the display panel. However, the display panel in the related art is prone to the problem that the alignment mark is black and difficult to identify, resulting in inaccurate alignment when the optical functional film is attached, which affects the performance of the display panel. ...
