A thin film transistor (TFT) array substrate is provided in which a sufficiently large contact area between conductive materials is provided in a contact portion, and a method of fabricating the TFT array substrate. The TFT array substrate includes a gate interconnection line arranged on an insulating substrate, a gate insulating layer covering the gate interconnection line, a semiconductor layer arranged on the gate insulating layer, a data interconnection line including a data line, a source electrode, and a drain electrode arranged on the semiconductor layer, a first passivation film arranged on the data interconnection line and exposing the drain electrode, a second passivation film arranged on the first passivation film, and a pixel electrode electrically connected with the drain electrode. An outer sidewall of the second passivation film is positioned inside an outer sidewall of the first passivation film. |
