Display device

A display device, comprising:

• a substrate;
• a scan line disposed on the substrate wherein the scan line comprises a gate electrode;
• a semiconductor layer disposed on the substrate, wherein a part of the semiconductor layer overlaps the gate electrode, and another part of the semiconductor layer extends outside the gate electrode;
• a source electrode and a drain electrode disposed on the substrate, wherein the gate electrode, the semiconductor layer, the source electrode and the drain electrode form a thin film transistor;
• an insulating layer disposed on the drain electrode, wherein the insulating layer comprises a via hole;
• a first transparent conductive layer disposed on the substrate, wherein the first transparent conductive layer electrically connects to the drain electrode through the via hole;
• and
• a second transparent conductive layer disposed between the substrate and the first transparent conductive layer, wherein the second transparent conductive layer and the via hole are not overlapped,
• wherein a projection of the second transparent conductive layer on the substrate has a first edge, and a projection of the drain electrode on the substrate has a second edge adjacent to the first edge;
• wherein the drain electrode comprises a transition edge, the transition edge being located outside the scan line and not overlapped with the second transparent conductive layer;
• wherein the drain electrode further comprises a fourth edge, the transition edge is connected between the second edge and the fourth edge, and the second edge and the fourth edge are not overlapped with the second transparent conductive layer;
• wherein the scan line extends along an extension direction, and the fourth edge is substantially perpendicular to the extension direction;
• and
• wherein the transition edge is one of an arc edge or an inclined edge.
