1. An organic light emitting diode display comprising:

  • a first organic light emitting element configured to emit light corresponding to a first wavelength region;

    a second organic light emitting element configured to emit light corresponding to a second wavelength region, a center wavelength of the second wavelength region being shorter than a center wavelength of the first wavelength region;

    a third organic light emitting element configured to emit light corresponding to a third wavelength region, a center wavelength of the third wavelength region being longer than the center wavelength of the first wavelength region;

    a fourth organic light emitting element configured to emit light corresponding to a fourth wavelength region, a center wavelength of the fourth wavelength region being longer than the center wavelength of the third wavelength region; and

    a hole injection layer disposed under the first organic light emitting element, the second organic light emitting element, the third organic light emitting element, and the fourth organic light emitting element,wherein the first organic light emitting element comprises a first assistance layer disposed on the hole injection layer, andthe fourth organic light emitting element comprises a second assistance layer disposed on the hole injection layer.
