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.
