Abstract

The embodiment of the invention discloses a display panel and a display panel manufacturing method. The display panel provided by the embodiment of the invention comprises an array substrate, a first electrode layer, a pixel definition layer, a light-emitting function layer and a second electrode layer. The pixel definition layer is provided with a first opening and a second opening. The surface of the side, away from the array substrate, of the pixel electrode layer is lower than the surface of the side, away from the array substrate, of the auxiliary electrode layer. The depth of the second opening where the second electrode layer is overlapped with the auxiliary electrode layer is reduced, so that the terrain of the second opening is higher than that of the first opening of the pixel light-emitting area, and the light-emitting functional layer is difficult to deposit in the second opening. Therefore, the phenomenon that a light-emitting functional layer material is deposited in the second opening can be improved, so that the resistance at the lap joint of the second electrode layer and the auxiliary electrode layer is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a method for manufacturing the display panel. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diode, OLED) have the characteristics of self-illumination, high brightness, wide viewing angle, high contrast, flexibility, low energy consumption, etc., and thus have received extensive attention. OLED display, as a new generation of display method, has begun to gradually replace traditional liquid crystal displays (Liquid Crystal Display, LCD), and is widely used in mobile phone screens, computer monitors, full-color TVs, etc. In a display panel with high resolution and high refresh rate, the brightness uniformity of the panel is greatly affected by the charging rate and voltage drop (IR Drop), and the brightness distribution usually shows a trend of being bright around and dark in the middle. [0003] At present, to ...
