Abstract
An organic EL display device includes a TFT layer, and a light-emitting element layer provided on the TFT layer. A light emission control transistor of the TFT layer includes a conduction electrode connected to a first electrode of the light-emitting element layer through a contact hole of a flattening film. The TFT layer includes an emission control wiring line connected to the light emission control transistor, an interlayer insulating film provided between the emission control wiring line and the conduction electrode, and a dummy electrode covered with the interlayer insulating film and having an island shape. The dummy electrode overlaps the first electrode, the contact hole, and the conduction electrode in a plan view.
