Abstract

An active matrix substrate includes a transistor, a pixel electrode, a drain lead electrode connected with the drain electrode of the transistor, and a contact hole connecting the drain lead electrode and the pixel electrode. A non-electrode through-bore portion is created on the drain lead electrode, and an opening of the contact hole crosses the through-bore portion. As a result, any changes or decreases in the contact area between the drain lead electrode and the pixel electrode may be prevented or reduced significantly, while the open area ratio can be improved.
