Abstract: Disclosed is an organic light emitting diode display including an organic light emitting display panel configured to display an image, and a lower passivation film attached to a bottom of the organic light emitting diode display panel. The lower passivation film includes a support film that is in contact with the organic light emitting diode display panel, and a stress adjustment layer formed beneath the support film and configured to reduce a bending stress to be induced in the organic light emitting display panel when the organic light emitting display panel and the lower passivation film are bent.
