Abstract

A display device includes: a display panel including a light emitting element and a pixel circuit unit connected to the light emitting element. The pixel circuit unit includes: a first transistor connected between a drive voltage line and the light emitting element and which operates depending on a potential of a first node; a second transistor connected between a data line and a second node; a first capacitor electrode connected to the first node; a second capacitor electrode connected to the second node and which faces the first capacitor electrode; a third capacitor electrode connected to the second node; a fourth capacitor electrode, which faces the third capacitor electrode and is connected to the drive voltage line; a bridge electrode, which connects the second capacitor electrode and the third capacitor electrode; and a shielding electrode, which overlaps the bridge electrode in a plan view.
