    Abstract: The present invention teaches a TFT array substrate and a display device. The TFT array substrate disposes second fanout lines of the fanout area on a first metallic layer, and disposes first fanout lines of the fanout area on a second metallic layer. Data lines and their corresponding second fanout lines, and second fanout lines and their corresponding first fanout lines, are connected together through vias. The first metallic layer has a greater surface resistivity than that of the second metallic layer. The present invention's fanout lines corresponding to a same data line have a significantly increased total impedance, and the impedance variation of the fanout lines has a less impact. As data signals propagate to the data lines through the fanout lines, the data signals' arrival times to the data lines have little difference, thereby enhancing the display quality, more reliable manufacturing process, and lower risk for short circuit.
