Abstract
A display device includes a substrate. The display unit is disposed on the substrate and includes a pixel circuit and a display element electrically connected to the pixel circuit. A driving circuit is disposed outside of the display unit. The driving circuit includes a thin film transistor. An inorganic insulating layer is disposed on the driving circuit. A power supply line is disposed on the inorganic insulating layer, overlaps the driving circuit, and is connected to a common electrode of the display element. An encapsulation substrate is disposed on the power supply line and faces the substrate. A sealing material is interposed between the substrate and the encapsulation substrate and overlaps the driving circuit.
