An array substrate, a display panel, a method for driving the display panel and a liquid crystal display device are disclosed. The array substrate includes: N rows of pixel units; N scan lines, each of the N scan lines corresponding to one of the N rows of pixel units, a switch is connected between two adjacent scan lines of the N scan lines; a scanning drive circuit configured to supply a scan activation signal to each of the N scan lines to activate a scan operation; a switch drive circuit configured to supply a drive signal to the switch between ith scan line and (i+1)th scan line in response to the scan activation signal of the ith scan line, to turn on the switch between the ith scan line and the (i+1)th scan line such that the ith scan line is in electrical communication with the (i+1)th scan line.
