1. An organic light emitting diode display, comprising:

  • a substrate including a plurality of subpixel areas;

    a plurality of pixel electrodes positioned corresponding to each of the plurality of subpixel areas on the substrate;

    a white emission layer formed on the plurality of pixel electrodes;

    a common electrode covering the white emission layer;

    a plurality of capping layers positioned corresponding to each of the plurality of subpixel areas on the common electrode; and

    a color filter layer including a plurality of filter layers corresponding to each of the plurality of subpixel areas,wherein at least two capping layers among the plurality of capping layers have any one of a refractive index and a thickness different from each other,the plurality of subpixel areas includes a red subpixel area, a green subpixel area, and a blue subpixel area,the capping layer includes a first capping layer corresponding to the red subpixel area, a second capping layer corresponding to the green subpixel area, and a third capping layer corresponding to the blue subpixel area, andthe plurality of subpixel areas further includes a white subpixel area with no capping layer thereon.
