Abstract

The invention discloses an array substrate, a display device and a fabrication method of the array substrate. The array substrate comprises a substrate part, a TFT (thin film transistor) and a data line which are formed on the substrate part, and a protective layer, wherein the TFT comprises a gate electrode, an active layer, a source electrode and a leakage electrode; a gate insulating layer is formed between the gate electrode and the active layer; the protective layer is formed between the gate insulating layer and the data line, and is directly contacted with the data line; and the protective layer and the active layer are arranged on the same layer, and made of the same material. The array substrate, the display device and the fabrication method have the following benefits that the protective layer is arranged between the data line and the gate insulating layer, the data line is directly contacted with the protective layer, no gap bubbles exist between the protective layer and the data line, and when the data line is etched, the protective layer protects the data line, so that breakage of the data line due to corrosion is avoided.

Description

technical field [0001] The invention relates to the field of manufacturing flat panel displays, in particular to an array substrate, a display device and a method for manufacturing the array substrate. Background technique [0002] Flat-panel displays have replaced bulky CRT displays and are increasingly embedded in people's daily lives. Currently, commonly used flat panel displays include liquid crystal displays (Liquid Crystal Display, LCD) and organic light-emitting diode (Organic Light-Emitting Diode, OLED) displays. The above-mentioned flat-panel display has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat-panel display market. [0003] An array substrate is an important part of a display, and a thin film field effect transistor (Thin Film Transistor, TFT) array substrate is a type of array substrate widely used at present. For the TFT array substrate, the TFT switch usually consists of a ...
