Abstract:
1. An organic light emitting display comprising: a base substrate; a driving transistor arranged on the base substrate; a first electrode electrically connected to the driving transistor; an organic light emitting layer arranged on the first electrode to generate a light; a second electrode arranged on the organic light emitting layer; an opposite substrate facing the base substrate and including micro-lenses to disperse the light generated by the organic light emitting layer, wherein at least one of the micro-lenses has a thickness that differs from another one of the micro-lenses; and a sub-electrode arranged on at least one of the micro-lenses, the sub-electrode making contact with the second electrode to be electrically connected to the second electrode wherein the base substrate comprises a plurality of pixel areas, the first electrode is arranged in each pixel area, and the sub-electrode is arranged between adjacent pixel areas in a plan view, wherein the micro-lenses comprise: first micro-lenses protruding from the opposite substrate and each corresponding to a respective one of the pixel areas, wherein each of the first micro-lenses has a first thickness; and second micro-lenses protruding from the opposite substrate and corresponding to areas between adjacent pixel areas, wherein each of the second micro-lenses has a second thickness that is thicker than the first thickness, and wherein the sub-electrode is arranged on the second micro-lenses.
