The present invention enhances accuracy in feedbacking a common potential applied to common electricity supply lines. On a substrate of a display device, a plurality of scanning signal lines, a plurality of video signal lines which stereoscopically intersects the plurality of scanning signal lines by way of an insulation layer, common electricity supply lines arranged in a matrix array which intersect the plurality of scanning signal lines and the plurality of video signal lines by way of the insulation layer, and a common bus line which is arranged around an approximately quadrangular display region to surround the display region annularly and is electrically connected with the common electricity supply lines are formed. The substrate includes a common sensing line which feedbacks a voltage of the common bus line to a common voltage generating circuit, and the common sensing line is connected to a side of the common bus line opposite to a side of the common bus line to which the voltage of the common potential is applied. Further, the common sensing line is configured not to stereoscopically intersect other conductive layer formed on the substrate.
