There is provided an active matrix substrate used in a display device or the like capable of making substantially uniform the level shift generated in the pixel potential caused by the distribution of resistance and capacity in each signal line. On the TFT substrate which is an active matrix substrate having a common electrode line formed parallel to the scan signal line, in order to eliminate non-uniformity of the level shift of the pixel potential generated at the scan signal fall, each pixel circuit is formed so that the capacity Cdg between the scan signal line and the pixel electrode becomes greater as electrically going farther from the scan signal line drive circuit and going farther from the common electrode line drive circuit. The present invention can be applied especially to an active matrix substrate used in a liquid crystal display device, an EL display device, and the like.
