THIN FILM TRANSISTOR, ARRAY SUBSTRATE AND DISPLAY DEVICE HAVING THE SAME, AND FABRICATING METHOD THEREOF

摘要

A thin film transistor is provided. The thin film transistor comprises an active layer (100) on a base substrate (500); an insulating layer (200) over the active layer (100), the insulating layer (200) comprising a source via and a drain via，each of which extending through the insulating layer (200); a source electrode (310) within the source via in contact with the active layer (200); and a drain electrode (320) within the drain via in contact with the active layer (200).
