Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel comprises a substrate, and a pixel definition layer located on the substrate; the pixel definition layer comprises a plurality of pixel definition blocks which are arranged at intervals; a groove is formed in one side, far away from the substrate, of each pixel definition block, and an auxiliary electrodeis arranged in each groove; and the bottom surface of each groove has hydrophilicity, and the inner side surface of each groove has hydrophobicity. According to the display panel and manufacturing method thereof provided by the technical schemes of the invention, the line width and morphology of the auxiliary electrodes can be regulated and controlled, the voltage drop problem is effectively alleviated, and then the display brightness uniformity of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED, Organic Light-Emitting Diode) has become the most promising new display device in recent years due to its advantages of self-luminescence, all-solid-state, high contrast, etc. In the field of large-size OLED applications, due to the gradual increase in the cathode voltage drop of the electrodes, the center of the display panel is dark and the display brightness is uneven. In order to reduce the voltage drop, an auxiliary electrode is usually provided outside the sub-pixel area, and the cathode is connected to the auxiliary electrode, which is equivalent to connecting a resistor in parallel to the cathode, thereby reducing the resistance value of the cathode. [0003] In the prior art, an auxiliary electrode is usually added on the pixel definition laye...
