ABSTRACT:
A pixel structure disposed on a substrate and electrically connected to a scan line and a data line is provided. The pixel structure has a reflective area and includes a common line, a semiconductor lower electrode, an upper electrode, a patterned dielectric layer, a reflective electrode and an active device. The semiconductor lower electrode electrically connected to the common line is disposed on the substrate within the reflective area. The upper electrode is disposed above and electrically isolated from the semiconductor lower electrode. The patterned dielectric layer with the micro-bumps is disposed on the upper electrode and exposes a part of the upper electrode. The reflective electrode is disposed on the patterned dielectric layer and the part of the upper electrode. Besides, the reflective electrode is electrically connected to the upper electrode. The active device is electrically connected to the scan line, the data line and the reflective electrode.
