Abstract: Provided is a display device. The display device comprises a substrate, and a plurality of sub-pixels disposed on the substrate and including alight emitting element and a sub-pixel circuit driving the light emitting element. The sub-pixel circuit comprises a driving transistor controlling a driving current flowing through the light emitting element, a first transistor and a second transistor connected in series between a first node, which is a drain electrode of the driving transistor, and a second node, which is a gate electrode of the driving transistor, to receive the same scan signal, and a gate auxiliary electrode disposed on a gate electrode of the first transistor or the second transistor. The gate auxiliary electrode is connected to the gate electrode of the first transistor or the second transistor.

Abstract: A display may include flexible substrate, a blocking layer on the flexible substrate, a pixel on the flexible substrate and the blocking layer, and a scan line, a data line, a driving voltage line, and an initialization voltage line connected to the pixel. The pixel may include an organic light emitting diode, a switching transistor connected to the scan line, and a driving transistor to apply a current to the organic light emitting diode. The blocking layer is in an area that overlaps the switching transistor on a plane, and between the switching transistor and the flexible substrate, and receives a voltage through a contact hole that exposes the blocking layer.
