Active layer, thin-film transistor array substrate comprising the same, and display device comprising the same

Abstract

Carbon allotropes, a thin-film transistor array substrate comprising the same, and a display device comprising the same are disclosed. The thin-film transistor array substrate comprising a substrate, a gate electrode on the substrate, a gate insulating film on the gate electrode, an active layer positioned on the gate insulating film and comprising a semiconductor material and a plurality of carbon allotropes, and a source electrode and a drain electrode that make contact with the active layer.

Description

technical field [0001] The present disclosure relates to a display device, and more particularly, to an active layer, a thin film transistor array substrate including the active layer, and a display device. Although the present disclosure is applicable to a wide range of applications, it is particularly suitable for improving the device characteristics of display devices by implementing an active layer comprising a carbon allotrope. Background technique [0002] With the development of multimedia, flat panel displays (FDP) are becoming more and more important nowadays. Along with this, various flat panel displays such as liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), organic light emitting displays (OLEDs), etc. are being put into practical use. [0003] The display device is addressed using a passive matrix addressing scheme or an active matrix addressing scheme using thin film transistors. In a passive matrix addressing sche...
