Abstract: An organic light emitting display device includes: a substrate; a first electrode on the substrate; a pixel defining layer on the substrate, the pixel defining layer defining a first opening which exposes at least a part of the first electrode; an organic light emitting layer on the first electrode; a second electrode on the organic light emitting layer; a thin film encapsulation layer on the second electrode; a sensing electrode on the thin film encapsulation layer; a low refractive index layer on the sensing electrode, the low refractive index layer defining a second opening which overlaps the first opening; and a high refractive index layer on the thin film encapsulation layer. A gap between an edge of the first opening and an edge of the second opening is constant irrespective of direction.
