Abstract: A display device includes a circuit layer and a light emitting element which is on the circuit layer and connected thereto. The circuit layer includes a transistor, an insulation layer on the transistor ad including a side surface which defines a contact-hole of the insulation layer at which a portion of the transistor is exposed to outside the insulation layer, and an upper surface from which the side surface extends, and a bridge electrode which extends along the side surface of the insulation layer and contacts the portion of the transistor which is exposed to outside the insulation layer. And a connection electrode which connects the light emitting element to the transistor. The connection electrode includes a first connection electrode which is directly on the bridge electrode and spaced apart from the portion of the transistor which is exposed to outside the insulation layer.

Abstract: A display apparatus includes a substrate. A first buffer layer is disposed over the substrate. The first buffer layer includes silicon nitride and has an atomic percentage of hydrogen bonded to silicon of about 0.36 to about 1.01. A thin film transistor is disposed over the first buffer layer. The thin film transistor includes an active layer. A display element is electrically connected to the thin film transistor.
