    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.

    Abstract: A display device includes: a pixel defining layer on a pixel electrode, and having a pixel opening exposing a portion of the pixel electrode; an emission layer on the pixel electrode at the pixel opening; an opposite electrode on the emission layer; a first refractive layer on the opposite electrode, and having a first refractive index, and a refractive opening that overlaps with the pixel opening; and a second refractive layer on the first refractive layer, and having a second refractive index greater than the first refractive index. A minimum gap between the pixel opening and the refractive opening in a plan view is greater than or equal to −1 μm and less than or equal to 2.5 μm, and a width of the refractive opening is less than a width of the pixel opening when the minimum gap is negative, and greater when the minimum gap is positive.
