On a display panel, a first scanning signal line drive circuitis formed along a side of a display regionand a second scanning signal line drive circuitis formed along the opposite side by the same process as pixel circuits. The size of a transistor included, the width of a wiring line, or the like, differs between the first and second scanning signal line drive circuitsand, and the two scanning signal line drive circuits have different sizes in a lateral direction. By this, the center of the display region matches that of a non-integral-type display panel, ensuring compatibility with the non-integral-type display panel. Moreover, by suitably determining the widths of or spacings between wiring lines included in the two scanning signal line drive circuits, leakage between the wiring lines and breaks in the wiring lines are reduced, improving yield of display panels.

In an auxiliary capacitance electrode of each pixel region, a side end on one side in a direction in which a drain electrode crosses an end of a gate electrode so as to enter from the outside of the gate electrode to the inside thereof is disposed inside of an auxiliary capacitance line, and a side end on the other side in a direction in which the drain electrode crosses the end of the gate electrode so as to go out from the inside of the gate electrode to the outside thereof is disposed outside of the auxiliary capacitance line.
