Array substrate and display device

Abstract

The invention provides an array substrate and a display device, including a thin film transistor, and the thin film transistor includes: a first conductive layer disposed on a substrate; an insulating layer disposed on the first conductive layer and a bare substrate; an active layer, which is arranged on the insulating layer; the second conductive layer, which is arranged on the active layer; the passivation layer, which is arranged on the second conductive layer and the exposed insulating layer, wherein the first conductive layer, the active layer and the second conductive layer are made of transparent and conductive carbon compound material. The invention can construct green and cheap devices, and reduce the potential harm of metal elements to the environment and human body.

Description

technical field [0001] The present invention belongs to the field of display technology, and in particular, relates to an array substrate and a display device. Background technique [0002] Currently used liquid crystal display devices or organic light emitting diode display devices contain expensive heavy metals such as indium, copper, molybdenum, and tin. These heavy metal materials have limited resources, high cost, and certain environmental pollution hazards. Therefore, reducing or even eliminating metal elements in display devices is a future development trend. For example, ITO (Indium tin oxide, indium tin oxide) electrodes have poor mechanical stability, and the increasing shortage of indium resources leads to continuous increase in its cost, and also brings metal environmental problems, so some alternative environmentally friendly electrode materials are urgently needed. [0003] In addition, as the size of traditional silicon semiconductor devices continues to shri...

Problems solved by technology

These heavy metal materials are limited in resources, high in cost, and have certain environmental pollution hazards. Therefore, it is the future development trend to reduce or even eliminate metal elements in display devices.

For example, ITO (Indium tin oxide, indium tin oxide) electrodes have poor mechanical stability, and the increasing shortage of indium resources leads to continuous increase in its cost, and also brings metal environmental problems, so some alternative environmentally friendly electrode materials are urgently needed

[0003] In addition, as the size of traditional silicon semiconductor devices continues to shrink, some unavoidable constraints continue to emerge, such as short channel effects, statistical fluctuations in doping concentration at small sizes, resulting in non-uniform device properties
