Abstract:
1. A display device comprising: a substrate having a first sub-pixel region, a second sub-pixel region, and a third sub-pixel region; a first electrode on the substrate; an optical distance controlling insulation layer on the first electrode at at least the first sub-pixel region; a light emitting structure on the optical distance controlling insulation layer, the light emitting structure comprising a first organic light emitting layer and a second organic light emitting layer on the first organic light emitting layer; a second electrode on the light emitting structure; and a blocking member between the optical distance controlling insulation layer and the second electrode at only the first sub-pixel region from among the first sub-pixel region, the second sub-pixel region, and the third sub-pixel region, wherein a first optical resonance distance between the first electrode and the second electrode at the first sub-pixel region, a second optical resonance distance between the first electrode and the second electrode at the second sub-pixel region, and a third optical resonance distance between the first electrode and the second electrode at the third sub-pixel region are different from one another.
