Transistor display panel having an auxiliary layer overlapping portions of source and gate electrodes

A transistor display panel comprising:

• a substrate;
• a gate line disposed over the substrate and extending in a first direction;
• a gate electrode extending from the gate line;
• a gate insulating layer disposed over the gate line and the gate electrode;
• a semiconductor layer disposed over the gate insulating layer;
• at least one auxiliary layer disposed over the gate insulating layer and spaced apart from the semiconductor layer;
• a data line disposed over the gate insulating layer and extending in a second direction crossing the first direction;
• a source electrode disposed over the gate insulating layer and the semiconductor layer, and extending from the data line toward the gate electrode;
• a drain electrode disposed over the gate insulating layer and the semiconductor layer, and spaced apart from the data line;
• and
• a pixel electrode connected to the drain electrode,
• wherein the at least one auxiliary layer overlaps a portion of the gate electrode and a portion of the source electrode in a plan view.
