1. A top emission organic light emitting display (OLED), comprising:

  • a substrate;

    a reflective layer disposed on the substrate;

    a first electrode disposed on the reflective layer, a contact surface between the reflective layer and the first electrode being a rough surface so as to reduce color shift with a wide viewing angle;

    an organic layer disposed on the first electrode; and

    a transparent second electrode disposed on the organic layer;

    wherein, as a bias voltage is applied to the top emission OLED via the first electrode and the transparent second electrode, the organic layer emits radiation in multiple directions, the reflective layer reflects the radiation toward the transparent second electrode.
