Abstract
A thin film transistor array substrate includes a base substrate and a thin film transistor, a second insulation layer, a first electrode and a second electrode formed on the base substrate. The first electrode and the second electrode are used to form an electric field, and the second insulation layer is interposed between the first electrode and the second electrode. The second electrode is a comb-like electrode, and located at a side of the second insulation layer away from the base substrate. The array substrate further includes protrusion structure located at a side of the first electrode close to the base substrate, the position of the protrusion structure corresponds to the slit portions of the comb-like electrode. A manufacturing method of a thin film transistor array substrate and a display device are further provided.
