Abstract
An active matrix substrate including, in each pixel area, a transistor, a pixel electrode (), a conductive member () functioning as one of electrodes of a storage capacitor, a drain lead-out () electrode connected to a drain electrode of the transistor, and overlapping with the conductive member (), and a contact hole for connecting the drain lead-out electrode () to the pixel electrode (), includes a gate insulating film () covering a gate electrode of each transistor, the gate insulating film including a first thickness portion () overlapping with at least part of the contact hole, and a second thickness portion () formed adjacent to the first thickness portion, and overlapping with the drain lead-out electrode, the first thickness portion () having a greater thickness than the second thickness portion (). This makes it possible to provide the active matrix substrate in which a short-circuit between the conductive member functioning as one of the electrodes of the storage capacitor, and the drain lead-out electrode (or the pixel electrode) is successfully prevented.
