Abstract: A thin film transistor and a preparation method therefor, an array substrate and a display apparatus. The thin film transistor comprises an active layer (4), an etched barrier layer (5) disposed on the active layer (4), and a source and drain (6) disposed on the etched barrier layer (5). The source and drain (6) are disposed on a same layer in a spaced manner. First via holes (7) are formed in the etched barrier layer (5), second via holes (8) are formed in positions in the active layer (4) corresponding to the first via holes (7). The source and drain (6) are connected to the active layer (4) through the first via holes (7) formed in the etched barrier layer (5) and the second via holes (8) formed in the active layer (4). Because two second via holes are formed in the active layer, a design value L1 of the channel region length of the active layer is shortened and a metal oxide semiconductor array substrate with a narrow channel is formed and the charge rate is high, which helps to improve the display effect.
