Abstract

The invention provides a display panel, a preparation method thereof, and a display device. The display panel comprises an active layer, an insulating layer, a source electrode, a drain electrode, a grid electrode and a pixel electrode. The source electrode, the drain electrode and the grid electrode are arranged on the same layer on the insulating layer, and the pixel electrode is arranged on thesurface, away from the insulating layer, of the source electrode, the drain electrode and the grid electrode.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] OELD (Organic Electroluminesence Display, organic electroluminescent display), also known as OLED (Organic Light-Emitting Diode, organic electroluminescent diode) display device, which has low energy consumption, high brightness, fast response time, wide viewing angle, weight Lightweight and other advantages have been widely used in various display devices recently. [0003] Since OLED is superior to LCD (Liquid Crystal Display, liquid crystal display) in terms of display color gamut, color depth, contrast and response speed, and recently, some companies have mass-produced large However, because the OLED manufacturing process is much more complicated than that of LCD, OLED has more film layers, and it is more difficult to improve the yield rate. It also requires more photomasks t...
