Abstract: An electroluminescent display device includes a substrate having an emission region and a bezel region, a bank layer that extends from the emission region to the bezel region, a plurality of signal lines which are disposed on different layers on the substrate, a first metal layer that overlaps the plurality of signal lines and has a step, a second metal layer that is disposed on the first metal layer, and an intermediate layer between the first and second metal layer. A step or curvature above the first electrode may be offset by the first intermediate layer so that incident from the outside is inwardly reflected. Therefore, a failure that a user at the outside recognizes the reflected light may be solved.

Abstract: A thin-film transistor includes an active layer, a gate electrode, a source electrode and a drain electrode. The gate electrode overlaps the active layer. The source electrode and the drain electrode are connected to the active layer. The active layer includes a source region connected to the source electrode, a drain region connected to the drain electrode, a channel region overlapping with the gate electrode, a first resistive region between the source region and the channel region, and a second resistive region between the drain region and the channel region. The length of the first resistive region is larger than the length of the second resistive region.
