Abstract

The embodiment of the invention provides a display panel. The display panel comprises a driving circuit layer, a first electrode layer, an auxiliary electrode layer, a pixel definition layer and an electronic transport layer. The driving circuit layer comprises a first surface and a second surface which are oppositely arranged; the first electrode layer partially covers the first surface; the auxiliary electrode layer partially covers the first surface; the auxiliary electrode layer and the first electrode layer are arranged on the same layer; a gap is reserved between the auxiliary electrodelayer and the first electrode layer; the pixel definition layer covers the driving circuit layer, the first electrode layer and the auxiliary electrode layer; a first through hole is formed in the pixel definition layer; and the electron transmission layer is arranged on the side, away from the driving circuit layer, of the pixel definition layer and connected with the auxiliary electrode layer through the first through hole. By setting the energy level difference between the lowest empty orbit of the electron transport layer and the work function of the auxiliary electrode layer to be 2.0 eVor below, the injection barrier between the auxiliary electrode layer and the electron transport layer is reduced, and the phenomenon that the display panel emits light unevenly is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display panel manufacturing method. Background technique [0002] In recent years, organic light-emitting diodes (Organic Light-Emitting Diode, OLED) have the characteristics of self-illumination, wide viewing angle, wide color gamut, low energy consumption, high efficiency, fast response speed, ultra-light and ultra-thin, and easy flexibility. , showing great application prospects in the field of full-color display and solid-state lighting. Due to the high resistance of the transparent upper electrode of the large-size top-emitting OLED panel, there is a phenomenon that the edges are bright and the middle is dark, which makes the panel emit light unevenly. Contents of the invention [0003] Embodiments of the present application provide a display panel and a manufacturing method of the display panel, which improve the non-uniform light emittin...
