An array substrate, a display panel and a display device are provided. The array substrate includes a plurality of gate lines and a plurality of data lines. The plurality of gate lines and the plurality of data lines define rows of sub-pixel regions, each of the sub-pixel regions includes two thin film transistors and a pixel electrode, and the two thin film transistors are both connected with the pixel electrode. Gate electrodes of two thin film transistors in an (n)th row of sub-pixel regions of the rows of sub-pixel regions are respectively connected with an (n)th gate line and an (N+1)th gate line of the plurality of gate lines, K≥n≥1, n and K are integers, and K is an amount of rows of the sub-pixel regions.
