Abstract: The disclosure provides a display panel, an array substrate and a fabrication method thereof. The fabrication method of the array substrate includes forming a plurality of first thin film transistors and a plurality of second thin film transistors on the first substrate. The etch stopper layer of the second thin film transistor is different from an etch stopper layer of the first thin film transistor, and a threshold voltage of the second thin film transistor is higher than a threshold voltage of the first thin film transistor. By using the disclosed thin film transistors to form the gate driving circuit, the second thin film transistor with a high threshold voltage can be used as the driving signal outputting transistor. The abnormal multi-pulse of the gate driving circuit and the display panel caused by the low threshold voltage of the second thin film transistors may be therefore avoided.
