Abstract
Embodiments of the invention provide a display panel, a display device and a manufacturing method of the display panel. The display panel comprises a substrate and a plurality of pixel units located on the substrate and distributed in a matrix mode. Each pixel unit comprises a transistor, a pixel electrode connected with the transistor and a common electrode arranged opposite to the pixel electrode, wherein the transistor comprises a grid electrode, a grid electrode insulating layer, a source electrode, a drain electrode and a semiconductor active layer; the pixel electrode is connected with the drain electrode through a first via hole; and the drain electrode comprises metal or alloy, the pixel electrode is a transparent metal oxide, the drain electrode formed by the metal or alloy is in direct contact connection with the pixel electrode formed by the transparent metal oxide, and a contact area is free of an oxide film layer of the metal or alloy.
Description
technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display panel, a display device, and a manufacturing method of the display panel. Background technique [0002] Due to the advantages of large area, high integration, high resolution and low power consumption, TFT-LCD (Thin Film Transistor-Liquid Crystal Display) devices, as the basis of a new generation of display devices, are receiving more and more attention. s concern. In the related art, a pixel unit of a TFT-LCD display panel includes a transistor, a pixel electrode and a common electrode. When the drain of the transistor is connected to the pixel electrode, it is easy to cause poor connection due to excessive resistance, which further causes poor display of the display panel. Contents of the invention [0003] The purpose of the embodiments of the present disclosure is to provide a display panel, a display device, and a manufacturing method of the disp...
