Abstract: The present invention provides a method for manufacturing a TFT substrate and a structure thereof. The method for manufacturing the TFT substrate arranges a connection electrode (83) that connects two dual gate TFTs in a third metal layer to prevent the design rules of a connection electrode and a second metal layer of the prior art techniques from being narrowed due to the connection electrode being collectively present on the second metal layer with signal lines of a data line and a voltage supply line so as to facilitate increase of an aperture ratio and definition of a display panel. The present invention provides a TFT substrate structure, which has a simple structure and possesses a high aperture ratio and high definition.
