Abstract: A thin film transistor is provided as follows. A first gate electrode and a second gate electrode are stacked on each other. A semiconductor layer is interposed between the first and second gate electrodes. A source electrode and a drain electrode are interposed between the semiconductor layer and the second gate electrode. A connection electrode connects electrically the first gate electrode and the second gate electrode. A first insulating film is interposed between the first gate electrode and the semiconductor layer. A second insulating film includes a first part interposed between the semiconductor layer and the second gate electrode and a second part interposed between the second gate electrode and the drain electrode. A third insulating film includes a first part interposed between the connection electrode and the second gate electrode.

Abstract: A display device includes a substrate including a display area and a non-display area adjacent to the display area. The non-display area includes a blocking region. An organic layer is disposed on the substrate. An emission layer is disposed in the display area of the substrate. An auxiliary pattern is disposed in the blocking region of the non-display area of the substrate. A thin film encapsulation layer is disposed on the substrate and overlaps the emission layer and the blocking region. The organic layer has a groove penetrating an entire thickness of the organic layer in the blocking region. The auxiliary pattern overlaps the groove. The auxiliary pattern includes a same material as a gate electrode disposed in the display area of the substrate.
