An array substrate for a liquid crystal panel includes a plurality of pixel electrodes corresponding to a plurality of pixels, and a common electrode provided common to the plurality of pixel electrodes. An alignment of liquid crystal is controlled by each electric field between each of the plurality of the pixel electrodes and the common electrode. The array substrate further includes a pixel selecting circuit, a line group for pixel selecting circuit, a potential applying circuit, a line group for potential applying circuit, and a common electrode line. The pixel selecting circuit sequentially selects pixels among the plurality of pixels. The line group for pixel selecting circuit is connected to input terminals of the pixel selecting circuit. The potential applying circuit applies a potential to the pixel electrode of a selected pixel. The line group for potential applying circuit is connected to input terminals of the potential applying circuit. The common electrode line is connected to the common electrode. The common electrode line extends in a region between the pixel selecting circuit and the potential applying circuit and in a region between the line group for pixel selecting circuit and the line group for potential applying circuit.
