Abstract
An organic light emitting diode display includes: a display module including a first organic light emitting diode to emit light with a first wavelength, a second organic light emitting diode to emit light with a second wavelength, and a third organic light emitting diode to emit light with a third wavelength; a phase difference layer including a first liquid crystal pattern on the first organic light emitting diode, and a second liquid crystal pattern on the second organic light emitting diode and the third organic light emitting diode; and a linear polarization layer on the phase difference layer.
