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.
