摘要： A thin film transistor according to an exemplary embodiment of the present invention includes an oxide semiconductor. A source electrode and a drain electrode face each other. The source electrode and the drain electrode are positioned at two opposite sides, respectively, of the oxide semiconductor. A low conductive region is positioned between the source electrode or the drain electrode and the oxide semiconductor. An insulating layer is positioned on the oxide semiconductor and the low conductive region. A gate electrode is positioned on the insulating layer. The insulating layer covers the oxide semiconductor and the low conductive region. A carrier concentration of the low conductive region is lower than a carrier concentration of the source electrode or the drain electrode.

摘要： 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.
