A thin film transistor substrate having improved display quality includes a gate line, a data line intersecting the gate line and providing a pixel region adjacent the gate line and the data line, a data pattern formed on substantially a same plane and of substantially a same metal as the data line, a thin film transistor connected to the gate line and the data line, a pixel electrode connected to the thin film transistor, an organic protective layer formed under the pixel electrode and protecting the thin film transistor, and an inorganic protective layer formed between the data pattern and the organic protective layer, the inorganic protective layer formed on the data pattern with a pattern similar to the data pattern. A manufacturing method of the above-described thin film transistor substrate is further provided.
