Abstract

The present application discloses a display panel and a manufacturing method thereof. In the display panel, an auxiliary electrode layer is arranged on a pixel definition layer, and a metal layer is arranged so that the second auxiliary electrode sublayer in the auxiliary electrode layer is connected to the The cathode layer is electrically connected, thereby reducing the resistance of the cathode layer, and also reducing the power supply voltage drop of the display panel, ensuring the uniformity of brightness in the display panel; in addition, the manufacturing method of the overall structure of the display panel is simple and efficient, Suitable for mass production.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Display (OLED) devices are self-illuminating, all-solid-state, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, It can realize many advantages such as flexible display and large-area full-color display, and is recognized by the industry as a display device with the most development potential. Existing OLED display panels generally include: a TFT substrate, an anode disposed on the TFT substrate, an organic light-emitting layer disposed on the anode, and a cathode disposed on the organic light-emitting layer, and a common cathode such as a top-emitting OLED display panel generally Use metal or transparent conductive oxide (TCO) with high transmittance;...
