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.
