1. A display panel comprising:
a plurality of pixel circuit parts each including a pixel transistor;
a first insulating layer covering the pixel transistor;
a second insulating layer disposed on the first insulating layer;
a plurality of light emitting elements disposed on the second insulating layer and each including a first electrode connected to the pixel transistor, a second electrode disposed on the first electrode, and a light emitting layer disposed between the first electrode and the second electrode;
a plurality of scan lines and a plurality of data lines connected to the pixel circuit parts;
a driving circuit connected to the scan lines and configured to provide signals to the pixel circuit parts; and
a conductive pattern disposed between the first insulating layer and the second insulating layer and including a plurality of through holes, the conductive pattern receiving a constant voltage,
wherein the first electrodes comprise first group electrodes spaced apart from the driving circuit in a plan view and second group electrodes overlapping the driving circuit in a plan view,
wherein each of the first group electrodes and the second group electrodes overlaps each of the light emitting layers,
wherein each of the first group electrodes and the second group electrodes are electrically insulated from the conductive pattern, and
wherein the through holes are spaced apart in a plan view from the second group electrodes.
