An organic light emitting diode display includes a plurality of switches, a plurality of organic light emitting diodes respectively connected to the switches, and a polarization layer on the organic light emitting diodes. The polarization layer includes a light blocking area and a plurality of color filters. The light blocking area has a plurality of openings respectively exposing the organic light emitting diodes. The color filters respectively fill the openings. A first dot opening includes a first red opening, a first green opening, and a first blue opening elongated in a first direction. A second dot opening includes a second red opening, a second green opening, and a second blue opening elongated in a second direction crossing the first direction.
