Abstract

The invention provides a display panel and a manufacturing method thereof, wherein a display area of the display panel comprises a first area positioned at the edge of the display area; and an auxiliary electrode and a light-emitting protection layer positioned on the auxiliary electrode are arranged in the first area, and orthographic projection of the light-emitting protection layer on the auxiliary electrode is partially overlapped with the auxiliary electrode. According to the invention, an auxiliary electrode is arranged in the edge area of a display panel, and cathode layer is in lap joint with the auxiliary electrode, so that the potential of the cathode layer is increased, the voltage drop of the cathode layer is slowed down, and the brightness uniformity of the display panel is improved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a manufacturing method. Background technique [0002] In flat panel display technology, Organic Light-Emitting Diode (OLED) display has many advantages such as thinness, active light emission, fast response speed, large viewing angle, wide color gamut, high brightness and low power consumption, etc., and has gradually become the successor. The third generation display technology after liquid crystal display. [0003] As the size of the display panel increases, the area of ​​the cathode layer of the OLED also increases. The transmittance of the cathode layer of the top-emitting OLED display requires that the cathode should not be too thick. Such a large-area cathode layer will inevitably lead to a decrease in the in-plane voltage, resulting in a decrease in the brightness of the screen and poor brightness uniformity. [0004] Therefore, there is an urgent need f...
