1. A display device comprising:
a display panel including a light emitting element and a pixel circuit unit connected to the light emitting element,
wherein the pixel circuit unit includes:
a first transistor connected between a drive voltage line and the light emitting element and configured to operate depending on a potential of a first node;
a second transistor connected between a data line and a second node;
a first capacitor electrode electrically connected to the first node;
a second capacitor electrode electrically connected to the second node and configured to face the first capacitor electrode to form a first capacitor with the first capacitor electrode;
a third capacitor electrode electrically connected to the second node;
a fourth capacitor electrode electrically connected to the drive voltage line and configured to face the third capacitor electrode to form a second capacitor with the third capacitor electrode;
a bridge electrode configured to electrically connect the second capacitor electrode and the third capacitor electrode; and
a shielding electrode disposed over the bridge electrode and configured to overlap the bridge electrode in a plan view.
