An organic light emitting diode display includes: a substrate; a first electrode (anode/cathode) on the substrate; a second electrode (cathode/anode) opposed to the first electrode; a first light emitting unit (220) and a second light emitting unit (240) between the first electrode and the second electrode; and a charge generation layer (230) between the first light emitting unit and the second light emitting unit. The first light emitting unit includes a blue fluorescent light emitting layer (B). The second light emitting unit includes a blue light emitting layer (B) and a yellow (Y) light emitting layer.
