Provide is a technique that enables to easily arrange driving circuits for driving gate lines within pixels, and to reduce display defects in a vertical stripe pattern. An active matrix substrate includes, in each pixel PIX, a pixel electrode 141, and a pixel switching element 10 that is connected with a gate line 13, a source line 15, and the pixel electrode 141. Driving circuit elements 110 of driving circuits for driving the gate lines 13 are arranged in a light-shielding area BM in a part of the pixels PIX in a display area. The pixel switching elements 10 in a row of the pixels in which the driving circuit element 110 is arranged are provided at non-uniform intervals, and drains of the pixel switching elements 10 in the same row are on the same side with respect to the source lines to which the pixel switching elements 10 are connected.
