Abstract: A pixel circuit including an organic light-emitting element, a switching transistor, a storage capacitor that stores a data signal applied via a data line, a driving transistor that allows a driving current corresponding to the data signal to flow into the organic light-emitting element, an emission control transistor electrically connected to the organic light-emitting element and the driving transistor in series, and sync transistors electrically connected to a bottom metal electrode of the driving transistor. The sync transistors include a first sync transistor electrically connected to a first one selected from a source electrode of the driving transistor, a gate electrode of the driving transistor, the high power voltage, and the low power voltage and a second sync transistor electrically connected to a second one selected from the source electrode of the driving transistor, the gate electrode of the driving transistor, the high power voltage, and the low power voltage.

Abstract: A display device includes a lower substrate that includes a side surface having a first inclined surface. An upper substrate is disposed on the lower substrate and includes a side surface having a second inclined surface. A first electrode is disposed on a surface of at least one of the lower substrate or the upper substrate. An auxiliary electrode is disposed on the first inclined surface of the lower substrate and the second inclined surface of the upper substrate. The auxiliary electrode includes a first portion corresponding to the first inclined surface, a second portion corresponding to the second inclined surface, and a bent portion bent at a predetermined angle with respect to the first and second inclined surfaces. The first electrode may be in contact with the bent portion on the first exposed surface to electrically connect to the auxiliary electrode.
