An active device array substrate includes a substrate, a first pixel electrode, and a first raised pattern. The first pixel electrode is disposed on or above the substrate, and the first pixel electrode includes a first truck electrode, a second truck electrode, and a plurality of first branch electrodes. The first truck electrode and the second truck electrode intersect to form a first node at the intersection of the first truck electrode and the second truck electrode. The first branch electrodes are connected to the first truck electrode and the second truck electrode to form a plurality of first domains, wherein the first branch electrodes are asymmetrical with respect to the second truck electrode. The first raised pattern is disposed at least between the first node and the substrate to form a first raised structure at least at the first node.
