A pixel unit comprising a first metal layer and a second metal layer. The first metal layer comprises a gate electrode and a first electrode. The second metal layer comprises a drain electrode, a source electrode, and a second electrode. The drain electrode overlaps the gate electrode in a first overlapping region. The source electrode overlaps the gate electrode in a second overlapping region. The second electrode overlaps the first electrode in a third overlapping region. The size of the first electrode approximates that of the second electrode. The first electrode and the second electrode are staggered.
