1. An organic light emitting display device, comprising:

  • a first electrode in an emission area of a subpixel;

    a pixel defining layer surrounding the first electrode in a non-emissive area of the subpixel;

    a light emitting layer on the first electrode;

    a second electrode on the light emitting layer;

    a first encapsulation layer on the second electrode; and

    a color filter on the first encapsulation layer in the subpixel,wherein the pixel defining layer includes;

    a first pixel defining layer;

    a second pixel defining layer on the first pixel defining layer, a width of the second pixel defining layer at any height thereof is wider than a width of the first pixel defining layer at any height thereof;

    a first metal layer on the second pixel defining layer; and

    a third pixel defining layer on the first metal layer;

    wherein a thickness of the third pixel defining layer is thicker than a thickness of each of the first pixel defining layer, the second pixel defining layer, and the first metal layer.
