    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.

    Abstract: An organic light emitting diode display device includes a substrate, a protection layer on the substrate, the protection layer including a trench pattern and a recessed portion, a first electrode on the protection layer, a pixel defining layer on the protection layer, the pixel defining layer defining an opening that exposes at least a part of the first electrode, an organic light emitting layer on the first electrode, and a second electrode on the organic light emitting layer. The recessed portion overlaps the opening and is spaced apart from an edge of the opening in a plan view. The trench pattern includes a plurality of trenches extending along a first direction. Each trench of the plurality of trenches is spaced apart from the first electrode in a plan view and has a concave cross-section.
